Eudes picked up a new to him 2016 ATS-V, and came by our shop a couple days later. He opted for the White Belt Performance Package, plus resonated downpipes for more turbo sounds. Final result was a very nice powerband, 100 whp above stock!

Testing continues on our Black Belt Performance Package. We started out by setting the new world records of 836 whp and 8.77 seconds in the quarter mile in January 2023. Now we’re up to 886 whp. We always know an engine is tuned properly when peak power is made at the exact same engine speed and repeats itself on consecutive dyno pulls. We can’t wait to watch this car run at the V-Racing Invitational in Texas this spring!

Hector from Ohio has one of the nicest and cleanest CTS-V Sports we’ve ever seen. We dyno tuned his car last year and power peaked at 410 whp. This week he upgraded to ATS-V turbochargers and we updated the tune accordingly. With no other changes, we picked up 40 whp!

Sal drove down from Michigan, so we could install our Blue Belt Performance Package on his M6 ATS-V. At 508 whp, this car will be an absolute blast to drive!

Darren from Ohio picked up a beautiful CT4-V Blackwing M6 car with the carbon fiber appearance packages. We added our White Belt mods and tuning, and he ended up with 475 peak whp. Now the car has a powerband that matches it’s handling and looks.
