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!

Timothy from Georgia just purchased a used ATS-V. It already had a competitor’s tune and was only making 6 pounds of boost. After installing our intercooler fill/bleed kit the boost returned, but the car was misfiring under boost. Timothy scheduled an appointment with us and drove up to Ohio. We found that the spark plugs were gapped too wide and didn’t have any dielectric grease. Correcting the spark plugs resolved the misfire, but the intercooler fill valve/port was leaking. We see many failures of these, so of course we keep them in stock. Once the fill port was replaced we were able to get a baseline dyno run and found the car was making 458 peak whp. After our custom tuning, we increased this to 502 whp. Timothy loves how the car feels now, and is already planning to come back and visit us again for his upgrade to Purple Belt.

Earlier this spring Cesar dropped by Exodus Performance in Texas for a partial Purple Belt Performance Package. He was still running factory intake, throttle body and catalytic converters at the time and made 546 whp. This weekend Exodus added catless downpipes and strapped it back to the dyno. We continued dialing in the tune remotely and turned up the wick to 605 whp and 630 wtq. Next Cesar plans to have our carbon fiber intake and Gigs ported throttle body installed, so stay tuned.

Last year Michael from Indiana stopped in for our Blue Belt Performance Package. This year he brought his M6 car back for an upgrade to Purple Belt. The result was a very smooth powerband peaking at 608 whp and 610 whp, running E49 fuel, and still using the factory airbox. We plan to see Michael again next year when he steps up to Brown Belt and joins the 700 whp club.

Kevin drove down from Michigan with his very clean 2015 CTS-V Sport. We installed our intercooler fill/bleed kit, Brisk spark plugs and performed a custom dyno tune. The White Belt Performance Package results were nicely improved WOT fueling, more horsepower and increased torque from 2,800 rpm on up!
