Rob drove his 2016 ATS-V A8 in from Tennessee to get the Blue Belt treatment with catted downpipes.  Now his car drives as nicely as OEM, and makes an additional 100 whp!

Casey from Louisiana worked with our recommended shop Exodus Performance to install and remote dyno tune the Purple Belt Performance Package.  Net results for this M6 car were 613 peak whp and 619 wtq.

Brian just picked up a 2023 CT4-V Blackwing with in the new Midnight Steel Metallic color.  We worked with HP Tuners to unlock his ECM, then he came back for the full Blue Belt Performance Package treatment.  30 hours later his car had picked up well over 100 whp and was a completely different animal.  Now Brian is ready to maximize his smiles per gallon rowing through the gears.

Dustin and Dominique drove in from Indiana for the Purple Belt treatment.  Two days later their 2016 ATS-V coupe left with 613 whp and 644 wtq.  The powerband was solid as usual, and WOT fueling looks like it was drawn with a ruler.

Two years ago we tuned Randy’s CTS V-Sport and he picked up nearly 100 whp in some parts of the powerband.  Last year when he purchased a beautiful ATS-V, he drove in from Kentucky to have us work our Blue Belt magic while the temporary tags were still on the car.  This year we upgraded him to Purple Belt and he put down a respectable 614 whp with stock turbochargers.  Next we installed TPC turbos and the power increased to 635 whp.
