Our friend Nick came here last spring for us to install our Blue Belt Performance Package on his clean M6 ATS-V. He loved the power gains but when spring came around this year he was hungry for more. Nick decided to step things up with our Purple Belt Performance Package and his car made 601 whp the go around! Needless to say, he was hyped about the power gains. But if we know Nick, we bet we will see him again next spring for our Brown Belt Package 😉

 

 

Brian brought his extremely rare Pedestal Edition ATS-V in for a Purple Belt Performance Package! 3,600 miles on the clock, a manual transmission, and the beautiful Bronze Sand Metallic paint make this ATS-V very special. Brian’s ATS-V made 621 peak whp and 615 wtq.

 

Donny brought his low mileage ATS-V coupe in from Illinois for Blue Belt upgrades. Even with Costco fuel in the tank, this car produced a very broad powerband with 508 peak whp.

Jeff drives all of his cars hard on road courses. He loves the handling and braking performance of his new CT4-V Blackwing, but like all of us, wanted more power. In stock form, his Blackwing put down 410 whp on the DynoJet. With Blue Belt mods and his Mississippi ethanol-free pump gas he made 479 whp. With the addition of our fuel cam and some custom dyno tuning he was able to hit 546 whp on E30 blend. Straightaways will be MUCH more fun for Jeff now!

Ken brought his new 2023 CT4-V Blackwing to us for the Blue Belt Performance Package. We dyno tuned using the new Tapout Tuning Module, and set him up with various calibrations ranging from 471 to 528 whp, all on 93-octane pump gas.
