Jesse from Texas worked with Exodus Performance to have his Blue Belt Performance Package installed and a remote dyno tune completed. The car baselined at 394 whp and ended the day at 495 whp, for a big improvement of 101 whp! And this was on EPA catted downpipes too.

Our good friend Paul from Ohio was the first ever ATS-V to run nine second quarter mile passes in the new ‘True Street’ category. He was slightly under the 3,950 pound minimum weight requirement, so he actually had to add ballast in his trunk that day. But like most of us, Paul always wants a little more. So our team installed Mace Stage 1 valve springs, titanium retainers and camshafts and strapped this car back on the dyno. The results turned out to be almost exactly what we expected. The engine made a little less horsepower and torque below 4,800 rpm. The power gains started at 5,300 rpm, and kept increasing as engine speed rose.

How much were the gains? If you make the common mistake of only considering peak numbers, all you’ll notice is the fact that power increased from 638 to 640 whp, which is statistically insignificant. Instead, look the graph at 6,000 rpm and you’ll see 10 more whp. At 6,500 the gain was 20 whp. And at 7,000 rpm it’s typically 30 whp (although we failed to spin the engine that high on our baseline pull). These are significant gains that can be felt driving the car, and will produce real results both on the street and at the track.

But wait a minute? Does this mean the car is now slower, since it has less bottom end power than it did before? Not at all. Once you consider the fact that the engine speed is nearly always above 5,500 rpm at WOT, you realize that any time you’re at full throttle with these cams, your engine will now be producing more power!

Scott from Missouri worked with us on a Blue Belt package with remote tune last year. This year he was looking to turn up the heat, so he dropped his car off for an upgrade to Purple Belt. Jorge knocked out the installation in no time and we did some custom dyno tuning which resulted in peak power of 612 whp and 637 wtq. We hope Scott remembers to leave the Traction Control enabled for his drive home!

Brian from Ohio just picked up this low mileage 2019 ATS-V coupe. He dropped it off with the temporary tags still in place and asked up to add approximately 200 whp. In order to accomplish this mission, we installed our tried and tested Purple Belt Performance Package. The results were a very smooth and bold powerband, with 624 peak whp. 2019 ATS-Vs are quite rare, and now Brian has the most powerful 2019 in existence!

Darius from Maryland purchased a totally stock ATS-V and made the decision to go full Purple Belt, plus Caddy Issues turbos. He and his son drove to Ohio and the world famous Jorge took care of the installation work. We strapped the car down to the dyno and it produced 677 whp and 693 wtq. This car made a bit less power than we usually see with these turbos, most likely due to the fact that he still runs factory camshafts and valve springs. Even so, these big numbers give Darius one of the top 25 most powerful ATS-Vs ever!
