Here's why my 302 horsepower V8 power C43 AMG was so slow and how I fixed it. We also retest 0-60 mph after just one simple modification/repair, and we go over the truth about how magazines get their performance test results and why you shouldn't worry too much if your 0-60 mph results suck.
Here is the Motor Trend article.

I'm super excited to announce a totally free way that anyone can support the channel!! I was approved for an Amazon Influencer account which allows YouTubers like myself, and other creators to earn a small commission from sales generated from people first clicking on my Amazon link, and then buying anything from Amazon. This doesn't cost you a penny as Amazon compensates the creators for driving traffic and sales to the site. So even if you don't buy the product or tool that I link in the video description box, you are still supporting the channel by shopping on Amazon after you clicked through any of my links. Each video will have either specific links to things I use or talk about in the video, or you will see my general LegitStreetCars Amazon link like this. https://www.amazon.com/shop/legitstreetcars
Next time you need car parts, tools, diapers, condoms, fidget spinners or anything on Amazon think of good ole Alex from LegitStreetCars.

    the half second is being lost on the cumulative wear of tranny bearings tires injectors valve springs, again tires but this time compound slash treadwear , also rumor has it that the media uses a rolling start to prevent traction factoring into the elapsed delta's current back to new…which i believe was 6 point 8ish up from 6 point 1.2ish thats 6.1, 6.2 not 6.12 that W0U1D B3 WEIGH DUMB….SPARk plug wear flex disc stretch alignment fuel condition/grade so so many things they conducted a test once on a track, took a brand new car and dyno'd it priior to creat or find baseline brand spankin new horsepower, after only a couple hundred miles they re tested on dyno and the car im not gonna lie, i dont recall but it was surprising lee high i believe it was around 20 to 30 per hundred
