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.

Scott brought his bone stock 2018 ATS-V coupe in for the Purple Belt treatment plus Aeroforce scan gauge and WOT Box. He left two days later with a nicely symmetrical 600 whp and 600 wtq and textbook perfect fueling.
