Hey guys, welcome back to legit streetcars and welcome to well my childhood dream I grew up Saturday and Sunday mornings watching car TV shows and basically it was this: They would have a table full of cool Parts a cool car behind them and they would modify them and that's what got me into all of this and as a kid I always dreamed of owning a Buick Grand National and and I have it I have a table full of parts I Always wanted to be a host on one of those TV shows and this may not be on TV but uh, but I'm I'm living the dream. So thank you so much to all of you guys out there who have subscribed and who enjoy the adventures of rescuing cars, fixing them and modifying them as much as I do anyway. I didn't uh, plan on rambling on about that, but in this video we will be modifying my Grand National exactly how I would want to modify it had I bought it new or even in the 90s when people were really ripping into these cars. Uh so I have basically every single kind of easy bolt-on that you could imagine and we're going to put them all on the car. in this video we're probably going to gain like I don't know, like 100 horsepower. It's gonna be a blast and uh, with that, let me let me show you what I got All right Hang on before I show you guys this I got to show you something we did to the interior of the Grand National and the exterior. We basically just cleaned it. My shop was packed and I went over to the Bays. So this is a new place where you can wash your own car indoors. They provide you with a bunch of stuff. It's a really cool concept. You rent the space so let me know if you guys have one of those near you. But we minted this thing out. We cleaned up the interior and it is just an absolute beautiful place to be. The seats and the carpet aren't new on this car and we got a new headliner and I wanted to get your opinion so I went with a black headliner. the factory one is gray but this is just such a Sinister black card that I thought it would be cool to get a black headliner and I kind of think this is how the Grand National should have been from the factory. so I love the black headliner. but I don't know what to do with the sun visors. um I don't want to mess with this sticker. it is perfect. I mean it's it, has perfect patina and this is so so neat. I didn't know these cars even had these. so when I bought the car and found this I'm like I'm in love even more so I don't want to mess with the sticker I could just get different sun visors in black but what do you guys think should I go with black sun visors or keep them gray? The interior is all about two-tone as you can see with the seats. Even the door panels are two-tone so it kind of matches. It could make sense, but let me know in the comments Peter How excited are you for this? It's like Christmas This is great. We got all this stuff in one box one day, we laid it out and we're both like yes, high fives each other. Like this is going to be so much fun and here we are. So I Just want to say big thanks to Aggressive Performance. They're my neighbors in Michigan and they provided me with most of the parts you see here. These guys are the Turbo Buick Specialists If you need anything turbo Buick related, they pretty much have it all. They have like 20 or 30 of these cars at their shop at any given point in time. Very, very nice people. They love the series and they wanted to help out with all this. So big! Big thanks to Aggressive Performance! I'll leave their link down below but check it out. This is what we got going on here. We have a hot wire kit for the fuel pump and this is a direct Plug and Play so really no wiring there. It's going to add more power to our fuel pump. We're going to be replacing the intake manifold gaskets because I think we have a leak. A triple gauge pod to house our scan master. So this is going to allow us to not only scan for codes and see a bunch of live data, but do a little bit of tuning as well. We have our Am air fuel ratio gauge. We have a true boost so we're going to be able to have a boost controller in the Buick so we can raise and lower the Boost at the push of a button. Uh And then the guys at Aggressive burn me a new chip for all of our modifications so we'll be installing that in the computer EGR Delete colder thermostat. We have a new O2 sensor 60 pound fuel injectors and LS1 mass airflow sensor a math translator. We have a 10-man cold air induction system and we have two little kids in a high performance candy store ready to install all of this goodness. But first we're gonna go for a little Baseline Cruise because we are going to be adding no power, more power baby! and we wanna we wanna feel the current level of GN power so that there's a good before and after. So let's go for a ride. All right guys. At the end of the last video, we had some performance issues. AFR went really rich. Uh, we had less boost. This is why there was a vacuum line that had come undone. It was kind of hacked together so we're definitely going to fix that. Uh, so now we're back to the way it is and it's essentially like stock power. It's running a little bit lower boost I think than Factory Um, but anyway, this is it. Yeah, it's just kind of like a very uneventful. Um, it's decent. Like the Boost kicks in eventually and it feels okay, but that's all the way down. right off the line and we're not like sitting there roasting the tires or anything. so I think we could do. We can do a lot better here. I'll just listen to it. From the outside you're rolling, you hit it. Yeah, it works. That's just nothing crazy and we gotta fix that. All right guys, Table of High Performance is there. Grand National is ready to go on the rack. We are prepared to perform some surgery. But first, uh, we have to drain the coolant. We have not done a coolant flush on this thing. It's kind of dirty. It's not bad, but we don't know how long it's been in this engine and we're gonna start off by removing the intake manifold which requires us to drain the coolant. All right. Let's see, we got for coolant. Yeah, it's green. It's a little cloudy, but not too bad. I'm glad we're doing it anyway. All right. So with the coolant drained out, we're going to remove both intake tubes and I'm gonna have to get a black coupler I don't like this blue right here. and then I Got to figure out if I'm painting this black. the Tin Man cold air intake is black I think I might like that I don't know I don't know. we'll see people. we'll see this guy is going bye-bye Forever This ripped up corrugated tube thing. Actually this entire thing is going away. Yeah, we have a new filter. We have a new LS1 mass airflow sensor and this goodbye All right. Next up, we're going to remove our coil pack and ignition module and you know what? I'm going to go ahead and replace these spark plug wires I Don't think there's anything wrong with them but we don't know the age. It's pretty inexpensive to do so get rid of those. Oh this guy lifts right out. Oh we are gonna clean up so much vacuum tube stuff. This engine bay is going to look good. so with that we're going to pull all these guys off. Some of these will be repurposed as well because we're gonna get rid of EGR unplug this guy and then the throttle cable and the TV cable for the transmission come off. This car does not have cruise control. It has basically zero options crank Windows Manual door locks The only thing it has is air conditioning. That's all I Need just like Keeps is all I need to treat my male pattern baldness which affects two out of three men by the age of 35. And guys, we can do something about this So Keeps is a subscription service that makes treating male pattern baldness easy and affordable by keeping everything online and it's as easy as a few drops on your head now. the sooner you get started, the better.

Now the best part is my viewers can claim a killer deal right now by clicking on my link down below or going to Keeps.com Legit. So don't delay. You can treat your male pattern baldness right now. You got nothing else to lose but more hair on your head. All right that slides out here we go. all right. So we're gonna take this upper plenum off now and reseal that as well. And the reason I'm doing all of this is because I think there was a vacuum leak in here. We had a lot of issues with high idle and I sprayed some starting fluid in here I ran out but when I sprayed it, the RPM raised up and I just want to start over after seeing those Rod caps. I mean they might not have sealed the intake properly. Pretty cheap thing to do as well. There's a sneaky bolt to the back of the plenum. There we go. There we go. Little baby plenum. So cute and little. All right. So here is the inside of our little plenum. We'll definitely clean this up. And this did have a throttle body warming circuit, so coolant used to go through right here and that's been eliminated for quite some time. I'm sure a little performance old school performance mod people would do so he didn't heat up your throttle body, but she's a little baby throttle body. A little room for improvement here, but most don't notice a big performance gain, so for now we'll leave it stock. All right. Say goodbye to this whole big chunk right here. We're getting rid of it. So this is the EGR valve right here. The nut is very difficult to get to. This had no gasket before so that was an issue and here is the solenoid for it. All right? Here we go. Goodbye, goodbye All right people. let's get this lower intake off. Oh, look at that slice in the hose. That is not good. We got to get a new one and then fix the reason why this happened. All right. There's our fuel return and here's our feed line. There we go. Oh, this O-ring has seen better days, that's for sure. Look at how crusty this guy is. That's what's kind of nice about replacing the intake manifold gasket. It gives you the chance to find all these little parts that are eventually going to fail. We already did the oil pan gasket, the valve cover gasket, so the engine sealed up really nice and now we're just finishing her off. All right. So a lot of times you can leave the fuel rail on when you remove an intake manifold, but we're going to be popping in new injectors anyway. so let's take the rail off. Foreign. just pull up from the injectors, pop them out and you're going to lose some fuel. Inevitable. But here is our rail. Oh, this is really nice. The injector harness Just Clips off like that and you can remove it separately. And for being so old, the wiring on this is in great condition. I Wonder if this has been replaced. It's not brittle or anything. This is nice. Good job. Good job! Buick Engineers on this. this little harness extension I Know you're still out there. You still got to be alive, right? right? I'm about ready to take the intake manifold bolts off, except this coolant tube will not budge. It's kind of rusted on there, so we got to pre-oil it. This stuff's kind of new I've been using it for a few months and it works really well. I'll leave you a link down below. All right, let's see if we can get this. Come on baby. No. Oh, we got it. Whoo! All right, that was tough. Oh my gosh, this thing would not budge at all. If you don't have any heat in the shop, definitely try penetrating oil before busting any heat out. Stuff works. Here's something else we get to remove. This is the factory boost solenoid so you can see here. It goes in line with the wastegate actuator and we're eliminating this. All right. There's that and that, and we're going to be eliminating some hoses here as well. So see ya! And we're going to be replacing the factory boost solenoid with our AEM solenoid for the true boost controller. and we're going to hide this thing and kind of clean some stuff up. So we're really, we're freeing the valve covers right now of really anything. All right. The intake is bare and ready to be removed. Well, you know, after we take those bolts out, you got it. You sometimes got to take the bolts out of the intake to remove it. All right, let's see if there's any loose ones. So far so good. And what's nice is this did have a little bit of a leak at the back of the intake, so we're going to fix that as well. We're pretty much fixing everything and adding a bunch of power. so this car was kind of stock. It has an aftermarket turbo and some exhaust, but I don't think it had much else done. And so these cars came with 235 crank horsepower. And after all the modifications we're doing in this video, we should be right around 450 crank horsepower. So we're adding about 200, almost doubling the horsepower of our Grand National in this video. With easy bolt-ons, this thing is going to be nuts. and if you're wondering, we're going to be running about 16 to 18 PSI of Boost From my research and talking with the guys at Aggressive, that seems to be a safe amount on a stock engine. This one does have forged pistons, but if you saw the connecting rod bearing video, you know it's it's kind of hurt. We don't want to. We don't want to go too crazy. We're just adding 200 horsepower to an engine that we just had to replace bearings in because they were improperly installed. That's all Now come on Intake, Don't fight me. we're on the same team. GM I Am your your father? Wait I am technically older than this car, but I was two when it came out. So I can't be your father. but I'm your cousin or your brother. Oh, just come off. I'm running out of stuff to say. Just come loose. Ah, this might need a little bit of persuasion. Oh yeah, she is glue down. Remember all the RTV on the oil pan I think uh I don't think we've seen anything yet. Usually these things just kind of. Pop once you break them free. But oh yeah, oh there we go. Okay, oh got you, you're mine. foreign. There we go. see you. So here is the gigantic gasket that we're replacing and then we'll be able to see our push rods and our lifters look at that. All right, None of these guys seem loose. We already kind of looked in here before. All right guys, check this out! I Found we have ported cylinder heads I Sent a picture over to the guys at Aggressive and they said yeah, these are the fully ported professional cylinder heads. So if you look in here we have different valves you can see at the back there where they used uh, different bits to Port out the cylinder head. So they've opened up these Chambers quite a bit and then they filled the EGR ports up with aluminum so they welded this, sanded it down and on this side as well. So this basically already had an EGR Delete except he left all that stuff on the outside which makes perfect sense. Remember it had no gaskets. yeah it was just flopping around right? but we but it wasn't really leaking like we would have heard that. Yeah if you guys were around for the video where the EGR thing was just kind of rattling around and had no gasket, that's why it was just there for like visual appearance. So I looked these heads up. they're like 2 800 heads. So if you took your Grand National heads and sent them into the company that does this, there's pretty much one major one. Uh, it's 2800 bucks plus tax and shipping. So we got like three thousand dollar heads. and they have ARP head bolts as well. So this is a fully built engine. It's got forged pistons and different rods, ported heads and everything. I'm going to go ahead and assume that it's got an aftermarket camshaft. Uh, we can't really tell from here, but the cam lobes look really, really nice. Everything looks to be in good working order. So cool ported heads. We're discovering even more about this thing as we dig deeper. and here is our intake manifold that we need to clean up and I'm going to replace the PCV valve. We should probably do that Grommet and let's see. yeah, I use a decent amount of RTV I was maybe being a little bit of a baby there too. This isn't too bad. off camera Peter is working on some wiring for the gauges, so he pulled out part of the harness for the AEM wideband that we're not going to be using just to kind of clean things up again and I'm going to go start stealing parts from our table. We got a thermostat, we have this intake gasket we need that I'll be back, don't worry. And then we got our white board while we work on a car. so we can write down parts so we don't forget. So this is what I need. We need a different size belt. We found out that the parts store gave us too long of a belt so we're going to get the proper belt and then a few little add-ons I'm going to replace the fuel filter again. We need a radiator cap. Heater is on the horn here ordering up all of our parts and let's get this thermostat out! I Did not get a new gasket for this so we got to figure out what style this uses. All right there we go. Oh yeah, we definitely need that little ring shot. And here's our thermostat so you can see here that's a 180 degree thermostat and the guys at Aggressive recommend we go a little bit cooler 160 degrees. Now on. Pretty much anything modern. You want to leave the factory temperature thermostat in there because there's no coolant running through the intake manifold on really most newer cars. Um, but back in the day, a little trick to gain a couple of ponies would be to run a cooler thermostat because the coolant's actually going through the intake charge. So if you lower that temperature and get cooler air in the engine, uh, that's going to make a little bit more power. I Mean we're talking a very tiny bit, but every little bit counts, right? All right. So I Just got done cleaning up the intake so we went from this nasty, dirty, crusty old thing all the way to this beauty right here. and I cleaned out the injector bores as well to fit in our new injectors with the new O-rings and all the RTV is cleaned up also so this guy is almost ready to go back in. but I Want to get a new one of these? I Cleaned this up but it's just it's very thin and it's kind of dented. so we have a new one of these coming in for 10 bucks and a bunch of other little miscellaneous Parts like our O-ring for the thermostat and everything else on the Whiteboard So that all comes in tomorrow, but we're moving along here. we're still working. Peter has been working on a wiring harness for all of the gauges, so here they are in the gauge pod. We're going to do the true boost up on top the air fuel in the middle. That one is the one I'm going to be looking at that I need in my peripheral vision the most. and then we have the scan gauge on the bottom and Peter did a great job on the wiring. so we've really reduced the amount of wiring big time. Like, yeah, that's how much came with all three of these gauges, but we didn't need all of that. so he was able to also connect some of these gauges together because they're all running the same power source and they barely use any current at all. So now we just have these really nice looms sticking out and there's only what, like three wires that actually need to be connected to the car. There's just the power of the ground and the data for the skin gauge. So here's our Aldl connector. This is our OBD diagnostic port and here is the orange wire here that Peter stripped back so we can splice in the data line into our scan gauge. We'll get into this stuff once we get the car running, but this is some seriously cool old school stuff. So inside of the math translator, we have some switches and some knobs and this was a very old way of tuning cars back before there was really any tuning software out there. so we're going to pick which mass airflow sensor we're using. We're using the three and a half inch LS1 and then you can turn knobs and switches to make it richer at idle, leaner at idle. There's also a wide open throttle switch inside of the translator so you can click that over to these different positions and this is how much more fuel fuel it gives you. This is so, so cool. So then because we're using the Turbo tweak chip, we can do some tuning in the car by literally pressing the gas three times and holding it and letting it go. And that changes your wide open fuel. Overall, first gear, we can do timing as well. This is literally like going back to the 90s as far as modifications and I love the fact that we're doing period correct modifications for the 86. Grand National A lot of guys will go with Standalone fuel systems and harnesses and stuff which is all fine. LS1 coils and all that good stuff. But honestly, I'm not going for any records in this. Grand National I Just want it to be a really cool, legit street car. and the fact that we're going to be able to tune stuff by like hitting the gas a few times and switching knobs under the hood. that's a lot of fun. I'm all about it. That's a beautiful crimp there Peter Look at that professional I Love it. I Get to be a wiring nerd some of the time. Yeah, a lot of the time. This is what I'm talking about. Peter is really good at wiring and running looms and whatnot. This is a very, very clean, clean setup. It's going to be reliable and it's not going to be open wires everywhere and butt connectors. And you see that? Yes, unfortunately, you see that a lot. All right. Here's our finished product for the Aldl connector and we even re-wrapped it in the factory tape so we'll just Mount that back up. And then here are our two power and grounds that are going to power up all three of our added gauges when the key is turned on. And here's the harness that's going to be under the A-pillar trim. So at this point we can go ahead and install the gauges. Either you want to do the honors of uh, mounting this thing, do I ever And this is supposed to match the factory interior as best as possible. Oh yeah, look at that. I Can't wait to fire this up. We just have a screw cap that we have to install and that is about it. Where'd you get that shirt? Oh this. Legitstreetcars.com Our first run of: Buick Grand National merch. We got people. Grand National merch. Everybody's got Buick Grand National Merch What? It's the latest thing. All right. That's our rendition of a cheesy 80s commercial to match the car. No way. But it is true. We have the Grand National featured on the back. or you can get your Grand National T-shirt with the car right on the front dead body not included. All of our merch is super high quality. Check it out. Link down below Legitstreetcars.com Whoa! Max Where did you get that awesome new white hoodie? I Checked this out I Found this fuse holder I Have no idea what this is for. Wires are exposed. These are power wires. We cannot have that. Yeah, it looks like it's it's. this harness right here going all the way. What? What in the world is going on? It goes right here and right here. Okay, this is constant power. This is for the uh. the engine computer. You disconnect this to clear out the codes and let's see. Yeah, this comes right out of the factory harness right here. This is a factory wire and then they added. they added this leg in and that 5 amp fuse so that they could disconnect the fuse inside the car and reset the engine computer without having to pop the hood. Man, did they have to clear out check engine lights that often that they had to relocate. Essentially a check engine light clearing switch inside the car by pulling the fuse. It? We're not. We're not doing that. This has Got to go. And this is where they ran this and the Boost line to the gauge that they used to have. Okay, yeah, goodbye sir. More stuff that we get to get rid of. All right, And then we're getting this guy out of here as well. Peace. Okay, so what they had going on here was the reference to the map sensor. This is the factory map sensor. I had a t in it spliced in for the boost gauge and this is that ghetto vacuum hose that was connected on the passenger side of the intake. Uh, yeah, this is all this is all going away. We're just gonna run one straight to the map sensor so it gets an uninterrupted signal and then this is the factory wiring going right to the power cable and disconnect that guy, then disconnect the little jumper they made and then we're just going to plug this in. So luckily they didn't splice into any of the factory harnesses. Is exactly what it's supposed to look like and now we can get rid of this entire thing. Get out. Okay, hang on. We got this and all of this that we just eliminated from the car. So I think there are six potential leak spots right here. This one was always popping off which would remove the reference to the map sensor. You really need that. so this is this is not good. and then these are open power wires that we just got rid of so the Grand National doesn't burn to the ground. All right, Since we're going around here kind of cleaning up wiring, let's see what we have going on here because we don't need these two anymore. Well, definitely this one because it's for the factory boost solenoid that we're getting rid of and I don't know there's stuff in here that looks to be not Factory So if we can cut this harness down and eliminate things we don't need, it'll just be that much cleaner. Okay, yeah, that's not. Factory What did they do? All right, Previous owner, What in the world is going on here? All right? I think I figured out what is going on here. Uh, this O2 sensor on the car has three wires. This is a heated O2 sensor. The factory O2 sensor only has one wire. It's a lot of the older O2 sensors weren't heated. That's just how it was. They were probably running race gas back in the day when it was leaded. That's all you could get when you wanted high octane fuel. It was leaded and you need a heated O2 sensor to run leaded fuel. So this is the ground. They spliced in power from the boost solenoid. Okay, and then one of the wires is the factory single wire from the factory. This should be the factory O2 sensor plug right here. and man, we can get rid of a ton right now because yeah, this is all we need. We got a factory single wire O2 sensor because I don't plan on running any leaded gas. No one's running leaded gas anymore and we don't need this connector for the Boost cylinder so we can get rid of that one as well. Man, we're gonna have like no harness left when we're done, but in a really good way. This is going to be so clean awesome. We get to get rid of a whole nother chunk of of aftermarket mess. There we go. We actually don't really need an O2 sensor at all because the turbo tweak Chip is going to make us run an open loop, but with an O2 sensor, we can at least monitor its readings I don't know. I'm gonna have a wide bin in the car so probably don't need an O2 sensor. but anyway. Uh, here's what we're gonna do. This factory wiring is already compromised. Obviously they spliced in here. It's got a cut right there and this is for that factory boost selling that we don't need anymore. That's where they grab the power. So we are just going to do a little sniperoo right there and goodbye to all of this. I Will just save this though because it is the factory connector for this harness and one day if someone was so inclined, they could splice it back in. but it's not going to happen. This isn't a low mileage garage Queen type of car. I Don't really care. All right. So we're just going to heat shrink these ends. All right. We ran out of butane, can't find the new can going back to the old school. Okay, so we have this all sealed up perfectly and we are just going to hide it in this existing Loom This is for the oil pressure gauge in the car. It's an aftermarket one because the Factory's engine computer does not monitor or display oil pressure and I do like to see that. So we're going to keep that aftermarket gauge in there. But there we go. that is now gone. Add a little piece of tape in there to hold it. Wow, we got rid of so much. look at this. we just have very minimal connectors here. All right. So we'll get rid of our three wire. O2 It's actually seems to be in pretty good shape. This thing is so nice, we're gonna save this. This will be part of our rescue kit when we go. Rescue An old abandoned GM car. There's a chance it uses an O2 sensor like this, All right. But we're going back in with the old school single wire and the car is going to be running an open loop with the turbo tweak chip. So technically we don't even need any O2 sensor. but with that scan Master we can read the O2 sensor reading. so why not? We'll just add it in here for a few bucks and look at this. This is all we have now. just the basics up front. We've cleaned up this harness tremendously. This looks so good. Oh, and check this out. We have the factory turbo Shield It was in the trunk and I just assumed with this aftermarket turbo is that it didn't fit anymore, but it totally fits just fine. So we are going to paint this. uh, it's basically from the factory the same color as this turbo so this is going to look really nice. It'll offer a little bit of heat shielding and then we don't have to look at this rusted hot side. I Mean that doesn't look good? This looks good. They totally tried polishing this out and then They gave up when they got to these little fins. So you can see here that they removed the coating from the factory and then it started to rust. All right. I Got it? We just got done eliminating a bunch of stuff from the engine compartment, but we do have to add a few things in. Here is our boost pressure line super long. We'll trim it to fit once we get everything in place. All right. So I got that almost? Peter Keep pushing push. Peter You can do it. You're doing so well. Keep pushing. Oh great job! Peter There we go. That's our O2 sensor wide band. We're having triplets. this is the last one. Got it? You did such a good job! Peter Oh man, you need a chiropractor now. All right. So this is the harness for the EGR that doesn't exist on this car anymore because they plug the heads so we're just going to make that disappear. We only need these two plugs back here and this one knock sensor plug which is already connected and then we'll take all of ours bundle together so we fit in through the firewall and we're gonna tuck these guys in behind this gigantic Factory Loom So we'll never see that there's everything we added. We'll hide it along the way. Then once the intakes in, none of this will be seen. Anyway, all right. so we're getting rid of this Crusty Grommet for the PCV valve. Oh, this thing is just coming off in pieces. I'll just take it out from the back. here. There we go. Now we have a nice flexible one All right. We got our new thermostat going in the intake and check this out. This was only like I think 10 or 12 bucks and it comes with the O-ring It's aluminum. I mean this is a big upgrade over this thing I think I could crush this with my own hands I I can't I was really hoping I could, but I'm not not that strong. Anywho, we'll get a little silicone spray here. Oh wow, what a nice upgrade. All right then we have our little clamp here and our Bolt All right, we're gonna install our EGR block off and even though it's blocked off in the head, there is still an intake Port that would leak if we don't install this guy here and we do have to use the factory bracket when I redo the motor eventually. I'll paint this up really nicely. Also paint the intake and the valve covers and everything, but we just need to pinch this a little and this little ear is getting in the way so we got to chop it off all right. A little bit of improper tool usage there at the end, but it accomplished what we needed to accomplish. Got rid of that super sharp edge and there we go. I Gotta say though, this doesn't look pretty, but when we'd redo the motor, we're just going to weld this up and then this will literally just be a beauty cover at that point and actually give you a nice shiny bolt to put in place of this stud when you do that. But we can't really do that now because then there would be no clamping Force at the top. So ugly. It is all right. So we're just going to make our own little gasket so we don't get an intake leak. So even with the head welded up, you would still have an intake manifold leak and this didn't have any gasket when I originally bought the car. so it's probably leaking all right. Looks so good, it looks so bad. All right, we'll just clean up our our TV job. All right. it's intake manifold time, we're gonna put a little bit of RTV here in the corners and then we're actually putting rubber seals in. uh, which is much more proper than just running a bunch of our TV pretty much have to build a wall of our TV to duplicate this seal and we were definitely getting seepage front and rear from this. so this is a nice little fix. All right here it is. That thing is not leaking anytime soon. All right now it is. Big Blue Gasket time I Wonder if this thing's reusable? It is a monster. The old one looks fine actually. All right, stay in the V. Oh there we go stay. oh it kind of Clicks in okay yeah ah, nice, beautiful. Now we have our cleaned up intake manifold. This is so satisfying! I Love this kind of stuff. Just kind of freshening up an old car that just needs a just needs a little love. That's all that's needed. Quite a bit of love, but man this Grand National is going to be nice and reliable when we're done and faster. Have I ever told you guys how much I love my Buick Grand National and I've wanted one ever since I was getting oh have I ever told you about the bureaucrat National that was in one of my neighbors garages when I was a little little kid. It was about five or six houses away from me and it was just under a tarp. I'd only actually seen it once and the guy was really mean. like even as like a 10 year old kid I just ride by and be like hey man, what's under the tarp I knew it was under the tarp but he still wouldn't show it to me. It was ridiculous and then eventually that guy just moved away I never knew what happened to that car but I think he was probably the only mean Grand National owner out there. Everybody in the Grand National Community has been emailing me and everybody's just super helpful and awesome. but that guy was not bad. Grand National owner all right. I'm putting the bolts back in the intake and I always take pictures of stuff because you forget little things that you could figure out later. but why waste time? So we have two bolts that are studs that looks like the fatter one. So here we go. that one goes there and the other one goes right here. All right. we'll give these guys a little Titan and we'll give it a little torque. this way it doesn't leak. They seem tight when I was taking them off, but we definitely had the intake manifold leak. Not Only was it leaking oil, but it was leaking air too. Last click, we're good. All right. before we go ahead and bolt this guy back on. Uh, we got to do some painting so we have time for it to dry. So as much as I love the look of this, we're gonna go satin black on everything and this. We're going to paint the original aluminum color so we gotta get to prepping, which in this case is pretty easy. We're just going to kind of scuff this up and we'll be priming everything so the paint adheres all right. So this is done and we just got to get some of this rust off. Shouldn't be too bad. Oh yeah, looking good. all right guys. Here is our paint booth. Everything is prepped and we're going to start off with some high temp primer. and normally I would be a little bit more worried about the floor, but it's all wet so nothing is going to stick to it. Actually, this primer pretty much looks like what the final product will look like. we're just going for like an aluminum natural finish. that's what it was from the factory and then both of these tubes are going to be satin black. All right. While that primer is drying, we're going to bounce around a little bit and replace our fuel pressure regulator so we're going to take this fitting off. We need this, but we don't need this. Be gone there. we go and check this out. We have a Billet adjustable fuel pressure regulator that's a boost reference regulator so it's going to increase fuel pressure as boost pressure goes up. and this is also from the guys at Aggressive. Such a nice quality piece. and what I love is that this is a direct bolt on so we don't have to drill into the firewall or anything. Comes with a new o-ring as well and you just put your tens back on. Okay, that's that all right. So we're just putting a little bit of Teflon tape on this fitting and we'll screw it right in. All right there we go. All right guys. Up next are the injectors and I was just about to rant and Rave about how awesome the factory rails are. Guys are running eights with these rails. Uh so I'm still gonna rant and Rave about them. they're awesome. Factory Rails from the 80s but someone mangled mine. Look at this. these two were missing injector clips and look at this. The injector seal is all ripped up like this is oh my gosh, this could have been causing an intake vacuum leak as well. This is really really bad. Oh man, look, this just gets worse. What in the world were they thinking with this? Oh man, what a shame. I'll try and fix it the best I can for now. All right? Uh Yep This o-ring's seen better days as well and this side has all of its Clips so that's nice. I Gotta find two clips though. that's what we're missing I Don't suspect we're gonna have any issues on this side, but what's nice is these injectors were all functioning properly. So these will go in our rescue car tool box that we bring around with us. We're slowly Gathering parts for old 80s American cars so that if we need them on the road one day for a future rescue, we have them. And we got a lot of stuff because we're placing even more sensors on the Grand National So we're going to have an idle air control motor and a TPS. Next up we have a high temp aluminum spray and I'm hoping this doesn't just look like the primer. now it does have aluminum look to it so that's nice. Oh yeah, that's what I'm talking about. I'm pretty sure that's what it looked like from the factory. This is going to look so cool all right. I Just finished up. look at this. Oh man that is gonna look so sweet I think they call it aluminum color or something like that and it really does look good. Can't wait to get this on! Can you show us your sweet tag? Alex Oh yeah, check it out for my tagging days. That would be the absolute worst tagger in the world. I Have zero artistic ability. If you guys have ever seen my handwriting, you might know. All right. here we go. This is a satin black. All right. Here's what they look like after one coat. So let's go work on the fuel rail and then we're gonna do another coat on these and then they're done. All right guys. New fuel injectors are going in. I think I found a clip that's gonna work. so this is Factory and this is what I have. Doesn't look the same but I'll have to find some online and order them. This should clip in. Yep. I Think these might be off the lightning, but honestly, these clips are a little redundant. I mean the fuel rail is getting bolted in and so the injectors are kind of sandwiched in there. Anyway, All right guys, the fuel injectors are done and there wasn't a whole lot I could do about this damaged part, but it doesn't make any difference. The seal is way below that and the clip still fits on. So we're good. and I Don't know about you guys, but I am getting very excited right now because we have the fuel rail going in the intake and everything around it. We're getting really close. We get to plug in our new Burn chip in the old ECU I Love this stuff so let's get some bolts in this fuel rail. Zip it down! It's so nice to be able to replace this nasty o-ring with a brand new one so this is the main feed line going back in. All right, we're done with the second coat and it's looking a little glossy, but it is going to turn more of a satin finish. hopefully soon here so we'll let these dry while we finish everything else. All right. So let's replace some sensors that commonly fail on these old 80s GM cars or really anything from the 80s and again, these aren't bad, but we're here. We want our Grand National to be reliable and these are inexpensive so let's just do it. This is the throttle position sensor. It's just a couple of screws and we will have to set this up later. but with the scan gauge and the car, we'll be able to see the voltage of the throttle position sensor through the gauge so we don't have to back probe or anything like that. And then it's just a simple adjustment by measuring the voltage and moving this around. It's adjustable all right. So this is just a preliminary Titan as we'll be loosening that right back up. Next up, we have the idle air control motor which when we first bought this car, we kind of messed up by having it out of the into take but still connected. and then we turn the key on here. I'll just I'll just let the previous footage speak for itself. Okay, okay, yeah, so we were being dumb and that's what happened I don't think there's anything wrong with this one though. it resets itself. but again, we're just going to put a new one in with a new gasket. All right, tighten this guy up in this baby little intake plenum is ready to go back on new gasket cleaned up plenum going on. Welcome Home Little buddy, you'll be under pressure soon. Under pressure. How did Vanilla Ice try to say he didn't copy the rift from Under Pressure I Don't get it, that's under pressure and Ice Ice Baby at the same time? Come on. Now it was such a good rendition. I might get flagged for copyright on that one who gets the money Freddie Mercury or Vanilla Ice Okay, going over it. We're good. all right. Let's plug in our throttle position sensor our idle air control so these are new. Our O2 sensor, is new. So much newness. All right. now. we have our cool little injector harness. Plug that guy in and these are actually numbered right from the factory so you can't mess this up. I Mean you could mess this up. You could totally plug them in wrong. But if you watch legit street cars Buick Grand National videos then you know that they're numbered so you won't mess it up. And really, who doesn't watch legit street cars? Buick Grand National videos. That's that would be so silly. All right. It's gigantic. coil and ignition module time. This is looking again like an engine. All right. Next up is our new upper radiator hose that's going right over our new aluminum thermostat housing with the new thermostat. All right, let's get our throttle bracket back on. How does this go this way? Yeah, that looks good. This guy through and this one too. All right. I've got our clip on. We're good. This guy fell off. There we go. All right. So Alex has been trying to replace his PCV valve for about two days. I Did it took so long for me to find a Grommet I have like four extra ones now. no one at the parts store could find one. I gave up on even telling them what kind of car it was and I just looked at them all myself. but I finally figured it out. We now have positive crankcase ventilation. Do you even know what part number it is? No, we'll We'll never be able to duplicate this again. I don't remember I can't help any of you guys Yeah! I threw out all the boxes and frustration so I have no idea what works. so good luck all right guys with the coil on I Connected everything and ran all of our vacuum hoses. so these are nice and neat. I'll show you guys the final product once we're done, but right now we gotta swap out the spark plugs. There we go. and these weren't horrible, but they probably haven't been done in 20 years or so. A little bit of oil on the threads that's okay and I forget what are these? Yeah, these are Auto Lights Auto Light 24s so we're gonna be going with some. AC Delco r43 Ts's aggressive had recommended these. they're one step colder, seems to be the go-to plug for the GN guys and I'm a GN guy I Can't believe I'm saying that I've always wanted one of these cars ever since I was a little kid I Cannot believe it's taken me this long to get one. but this is definitely one of those cars that brings me like the most. Joy Like every time I see it. it's one of those like you walk away from it after you park it and you just turn around and stare back and you're walking backwards. and then you you trip on something and your wife laughs at you for being a dork. It's one of those cars, all right. She's torqued all right. So I finished up all of the spark plugs and we're going with some black. AC Delco spark plug wires. The ones that were on here again don't know the age. They were gray and they got dirty so they just looked like dirty spark plug wires and I like black ones better. So here are the old ones and here are the new ones. They just look better. Luckily the coil is labeled so this is six two four. So I believe this is the shortest of the bunch. Here we go. It's a positive click. One of the best sounds when you're working on a car is that positive engagement of the spark plug wire on the spark plugs. I Hate cheap wires that are questionable. Where you're like, is that on and then you're tugging on it and taking it on and off a million times and you're making it weaker and you're worsening the connection trying to figure out if it's connected? That's it's not cool, all right. Our black spark plug wires are done nicely, organized and neat. and kind of a last minute decision here. but I'm going to swap out this alternator I Don't like that noise. So 100 bucks I got a new one, a reman one so let's swap it. Uh, we've already been here before. We swapped out the tensioner and had to remove the alternator for it and the core on the alternator is only 16. So I am currently making a bin of Grand National Parks parts that we've removed from the engine that really didn't fail and I'm gonna put them in the trunk and I'm just gonna keep stuff with me just in case. Sometimes those parts store alternators fail like quickly. so I'm gonna have this on hand. I'll keep some tools in the GN It's just what you do when you got an old car. All right. And while we're here, we actually ran our wiring for the hot wire kit for the fuel pump which I'll show you guys in the back, but it's going to get power now directly from the alternator. The new alternator I mean disconnect the power. By the way, when you're doing an alternator, there we go. Now this should come out Italian Power there we go. Okay, in the trunk you go little buddy. How did that snag itself? Hang on Hotwire kit I Will give you power soon. get off. We're going back together with a triple tested remanufactured alternator. I Don't really trust these at all. I Think they just replace the one part that went bad and then what did they hook it up to a testing machine? Test it once it's already hooked up. so they just press the test button again and again. Why don't they just quadruple or quintuple? Is that it? Yeah, I mean just one up the next guy with how many tests, how many times you've pressed the button and it said yeah, it's good quadruple quintuple sextuple? Yeah. Quintuple tested as marketing for you right there people. All right. We're going back together with this super long nasty bolt because I don't have another one that'll work. but when we redo the engine, we'll get some nice Hardware Okay, I'm gonna be gentle on that one. The last guy tightened this up so much he cracked the tensioner. The Alaska I also put the rod caps on wrong and almost destroyed the entire engine. So I don't know. Yeah, this bracket is a nightmare. One finger is not gonna do it. Peter You're gonna have to put the camera down and get a pry bar. if you just pull up on the intercooler. that is the ticket. The ticket to success and fame and fortune is just lifting up on the Grand National intercooler that's lined her up real nice. Now we just do one of these. It's the secret of the Grand National secret. National Treasure This is a National Treasure Grand National Treasure That's right, When does the Grand National get like the proper recognition like Right up there with like American Pie like the Grand Nationals American man I Guess the only part that's not like super American is like the fact that it's boosted like that. Wasn't a really popular thing originally. But yeah, you don't. You know what a V8 is. Damn what you got under there six sixes. What are you? German Yeah, that's exactly what happened back in the day. Turbo V6 GM Guys were discriminated upon by the American V8 Guys All right guys. So right now we are going to hook up our hot wire kit. So here's our Factory lead for the back of the alternator. and here is our hot wire. So with Factory fuel pump wiring, you can lose some power through all of the old wiring and there's a lot of it going on. So we are going to replace the power feed only with this so that at wide open throttle we're not losing any voltage or fuel pressure. All right. Then we just ran the harness underneath the car along the fuel lines. Like so all right. So then this kit from Aggressive is so nice. it's made for this car. All we're going to do plug in our Factory harness to the hot wire kit and then bam right in. And now we just got to find somewhere to mount this guy. and right here. Maybe All right. So we're just going to drill this out a little. See now, one more maybe Perfect All right, we're going to loosen up this strap for the gas tank. All right, the exhaust is going to hold it up. We just need to swing this out temporarily. now. let's remove this Bolt This is definitely never been removed since 1986. we just broke Factory Torque right there. all right. now. With that out of the way, we're going to bring this Over Yonder to the back side and then reinstall the bolt. Like so okay. I Can just reinstall our fuel tank straps and there we go. Perfect. Very. Factory This is still being held in and we'll just give this a few zip ties and just like that, our hot wire kit is complete and if you guys were around for the previous Grand National videos, you know we already dropped the tank, we cleaned it and we installed a 255 liter per hour fuel pump and a new sending unit. So now we are really good to go! I Just pulled the plug on the rear diff nothing came out I Peeked in there. it is definitely a little low so we'll top her off. now. when it starts running out, you know you're full. Okay, that sounds good. Yeah, sorry. and actually gear oil smells about just as bad. Wow. Okay, are you serious? this is really low. Check your fluids people. I Should have done this when we did all the other maintenance on the car. I Just kind of forgot we're good. It took one. definitely not good, but probably not low enough to cause any real damage, especially considering how little we've driven it. All right. There we go. All right guys. I Gotta fill this up with some anti-freeze and then we have our intake system to install that's all painted our turbo cover. This engine bay is gonna look so so good. We removed a lot of garbage which I Want to show you guys after this drink up national Grand Treasure National Oh I Forgot to tell you guys, we went with a little bit of a shorter belt I Guess when you ask for a belt for a Grand National at the auto parts store, they actually give you the wrong one. it's supposed to be shorter. so the guys at Aggressive told me which part number to get so we had a 640 before. That's what they gave us when we were in. Wisconsin and we found this car. but you're supposed to go with a 630 because we're still getting a little bit of squeak noise I Think that might have been it, but it's not too tight. It's perfect. all right guys, it's intake time so we're going to be installing the cool air by the Tin Man kit. So I guess this thing has been around for a while I Spoke with the owner. very cool guy and everything is labeled so this one says two. MAF So it's pretty easy to figure this out so it'd probably be hard for you guys to see. but we did have to bend a tab down here and then we installed this corrugated a tube down here and then I have to feed this in through the bottom. All right. So now we're going to install this piece here and the sticker faces up. I Sprayed a little bit of silicone here so this should go over like that and we'll give these clamps a little tight. So then part of the Tin Man kit comes with this coupler. here. We're going to put our intake air temperature sensor right in here and it's a really nice tight fit. perfect and now we can slide this on and it's very loose. I Thought this was a little weird. so I give them a call. I Guess the manufacturer changed the inside diameter but they've been like this for years. All we have to do is just kind of tighten it up, tighten it down. Oh yeah, not going anywhere. That's perfect, all right. So this is the Tin Man kit right here. this from this part down with the filter and then this is our LS1 mass airflow sensor that we got from Aggressive with their little silicone adapter and we're going to slide that guy in. and I think they do have a mathless kit which I may go to eventually because I kind of don't like this big section right here. I'd like it to just be one nice tube and I'm used to going speed density on my boosted stuff as well. All right. So before we can plug in the mass airflow sensor, we need to make sure that our map translator is set properly. All right. Cool Tells you everything you need to know right here. All right. So we have Mode One, two, three, four, uh, base math and then wide open throttle so we have the 3.5 inch mass airflow sensor. uh, base is zero, Number one is ten percent richer at idle, two is ten percent leaner at idle, and then it just tells you everything else you need to know here and then you can switch it up wide open throttle as well. We're going to go with no changes right now because we have the burn chip for exactly the modifications we have and that's how they ship it to you. It's all at zero and then standard chip is on, on off, we have on on off off. What does that mean? Do you know what that means? All right, we figured out what's going on here. Uh, we have the paperwork here for the math translator and you can see here. These are different chip types so the extender, the extender, extreme, and then all others turbo tweak. That's what we have so we need on on off see if my fat finger can do that. There we go on on off. we're all set. I Feel like a real tuner now I'm an 80s 90s tuner at this point. This is so cool. Like yes, you can go to a Holly Kitten and then just it's like an LS at that point. but I'd much rather pull over on the side of the highway after making a pull, pop, open my math translator and switch over some knobs and buttons and then reseal it again. How many of you guys just left one screw in here? Be honest. All right. So at this point we have to mount this guy so it looks kind of neat and I think this area right here might be our best bet. Yeah, tucked in just like that, that looks pretty clean. I Really like that and we should have plenty of harness. We have plenty of harness. It's like did they have a math translator or what did they have right here? It was more like a triangle or something. Grand National Guys, what? What would have been this shape right here? also I'd like to add that I added this corrugated tube. math translator doesn't give you that I Love the Nostalgia behind this math translator, but there's not too many weirdos out there like me. Like they could just put the knobs on the outside or like make this weatherproof. That's like this has been the same thing since like 1982. Uh, We're Not Gonna drill any more holes into the Grand National we're just gonna stick this on and I did this with the boost solenoid for our controller as well. which I got to show you guys where we hid that. All right? So now without drilling any holes, stick it on right there. she's not going anywhere. So this is the factory harness. it's going to plug in like so and now our LS1 mass airflow sensor can plug in like that. All right guys, here's our satin black tube that's going in. there we go and then I think we just got to twist this guy over here like that. I Believe All right. Then we got our black silicone here with some Mishimoto clamps. All right. All right now we have our little piece. This came on the car and we just painted it. Fitment's not the best on this guy, but we know it works. Get on there little buddy. Oh come on. Oh yeah, there we go one. that's it. It says he doesn't even need clamps. it's so so tight on there. All right guys. We do have to get some different clamps at some point. If anything, we should have these clamps on the air filter side. I Don't think it's going to make any real difference, but these were painted black and they look cool. They came out the car about those clamps. We got some good ones on here to hold in our boost so everything is solid. The intake is mounted up the Tin Man is fully installed and this is how the air filter looks so it does look low. except I Learned that I'm missing these large air dam pieces. so I have those on order. We're going to be installing those in the next video and then it'll pretty much cover that up. All right guys. Here we go. We're installing this beauty and if this was coated I would potentially leave it take this bracket off or something, but this is what we're covering up with this. So I am all about that and we found some really nice stainless Hardware as well. Oh, this looks good. all right. Beautiful. There's the brown popper right there. This is so cool. This looks so good. Oh my gosh! I Love the black. Oh I Can't wait to eventually go. Speed density though. I will say that, but whatever. right now this looks so much better than before. We cleaned this up like crazy. Alright guys! So we went from an unorganized kind of cluttered up hobbled together engine compartment all the way to this. Ah, this is beautiful. We have our awesome Billet fuel pressure regulator right here and it's just gonna get better once we eventually fill the ports for the EGR We'll get rid of this guy here, but we had all the EGR stuff, a bunch of vacuum lines and wires that weren't doing anything at all so we freed up a ton of room. We have our super retro math translator here. Oh and let me show you guys where we hid the boost solenoid for the true boost and it's right in here. See, there's a little air intake for it and then we have the hoses hooked up. One of him goes to boost so up here and then the other one goes right here to the wastegate so it's going to intercept that boost pressure. It's going to bleed it off, which is going to then basically send a false signal to the wastegate and it's going to tell the wastegate it needs more pressure. I Mean it's all mechanical. It's not actually going to communicate any of that, but that's what a boost controller does. It bleeds off the boost reference to the wastegate so that it stays closed and makes more boost. Boost Boost Boost Drink every time. I Say boost. but we have our new spark plug wires as well and everything is just routed a lot better. There's a lot less clutter in here and overall I'm super happy we haven't cleaned or detailed anything yet either. But looking sweet? All right. You ready for this? Let's do it. Let's see some gauges. Oh baby. so cool. No way. look at that OBD1 it says Buick Get out of town. Oh man. all right. So right now we have to. uh, set the throttle position sensor. Oh man. look at all this information. There we go. So what are we supposed to be at? Um, 0.4 to 0.46 All right. So I'm gonna go and move that and you let me know where it's at. All right? So I've loosened this guy up. So I'm gonna move it Peter's watching the gauge. Where are we at Peter or what? All right? I think we gotta go this way. 34. 40 too far. This is tough like you let go and it moves a tiny bit and you're done. So I'm going to make this tighter so it'll actually stay in place. All right. We're in four two, locking her down with the world's tiniest screwdriver. All right. Cool. So our TPS is set at idle now. go wide open throttle. It should be uh, 4.20 to 4.6 So uh, is the carpet getting in the way or anything? Because we're almost there. right? Oh, there we go. 4.21 That's good. There we go. Perfect. Perfect. Okay, sweet. Now go back. let's see if the ah awesome look at that 80s technology. This is so cool. All right. So right now we have to install our computer chip. Our turbo tweak computer chip from aggressive and you have to disconnect this power to the ECM to reset it. All right? So since we have no power going to the computer right now, we can take out this chip. I'm assuming this is an aftermarket chip, Let's see. yeah. 36 pound injectors? That's what we thought they had I Don't know what a and a HP means I Have no idea, but this is an old chip and we're going with our new chip. Look at that. 60 pound injectors 16 to 18 PSI 18 to 20 degrees of timing. Oh yeah, now we just install it in reverse order. And unlike the C4 Corvette we don't need to put a factory chip back on on that one. We had a chip rattling around in there that was supposed to be put back. but anyway, this is easier. Now we're just going to reconnect our power to the computer. There we go. All right dude. Ready for this fire up. Let's do it. Let's do it all right? Yeah, Okay, okay. spoke a little too soon there Peter uh yeah, with that new chip, it's gonna be kind of weird I think for the first few starts, let's do it again. There we go. Uh, we definitely gotta mess with our fuel pressure. We're only at 20.

uh we gotta set that with this guy off. Oh, we're leaking a little fuel. You know what? Turn it off? Peter Yeah, we're leaking a little bit of fuel. There fuel pressure is way too low. We got to fix that. All right guys. I Just had to tighten up this fitting a little bit. Uh, vacuum line off. Let's fire it up again. That's how you set the adjustable regulator. You have to have the vacuum line off. so let's see what we have now. Go ahead. Peter All right, it's going up. What are we gonna have? So we want our base fuel pressure to be 43 PSI with a vacuum off? Man, this thing runs so bad it should run. I Mean we're a little low on fuel pressure? How is it in here? It's like it's it's measuring as low. Oh wow Yeah, this is really rich. Oh man, and we have second. Oh okay, so the fuel pressure is getting up there. now it's getting close. I Put this back on. but yeah, this is actually where it should be. Roughly with the vacuum on, it'll go down from the 43. so we want it to be around 38 PSI with the vacuum connector. So I think we might just coincidentally be the ballpark. This has kind of a Miss Give it a little. oh yeah, breaking up sounds like it's got a two-step Oh Oh yeah. wow. Okay, all right. yeah. shut her down. Shut her down. Okay, yeah, okay, it's not running the best. Fuel pressure seems decent though. So what? Oh, did it just puke all over the eclipse? Oh wow, it's not cool. Wow man that is bad I hate when you have an issue like this right after you do spark plugs. Luckily, these aren't that hard to replace again, but uh, we don't want to run it like this. We got to figure out what's going on from having worked on a lot of older GM stuff. This feels very mass airflow sensor to me even though we have the brand new LS1 mass airflow sensor but this is the box that I got. it used to say 85 millimeter and now it says three and a half math. We ran the par numbers and everything looks good, but I'm just curious if we switch this guy to number six that sets us up for the 85. yeah, see number six here. 85 millimeter sensor. Let's see how it runs now. All right, fired up Peter Fireball Okay, Idol's really nice. much better. How's the AFR Uit 14-4 when it first started? but yeah, it said 12. Okay, yeah, shoot, it was better initially. Yeah, I'd say we definitely made a change. You know what? Let's shut it down. let's put the stock mass airflow back in. All right, We just installed the factory mass airflow sensor so this goes directly into the factory harness. No map translator anymore. Uh, let's see what happens. I Gotta say it idles and starts up beautifully. We never had it this good before. Uh, there are also no more vacuum leaks before. we could always hear some hissing. So this is nice and idles down. It's beautiful. Oh yeah, oh yeah, that is great. We're back. I was AFR Now it's rich but it's like startup Rich 11 times. Yeah, Oh good, good. Okay, Oh yeah, we made a big difference. Yeah yeah, there we go Okay cool. So we can actually run it with that one because uh, it's not calibrated with the new chip to get. If we get into boost, they'll probably go super lean. So let's go get a new mass airflow sensor. All right guys! I Just went to the auto parts store, picked up a new LS1 mass airflow sensor. This one is aluminum. uh, looks pretty good and it doesn't require this little jumper here. That'
