We worked Tim and Lilly at Exodus Performance in Texas to remote tune Aaron’s 2016 ATS-V A8. He had installed a ported throttle body and catless downpipes. Baseline numbers were 403 whp and 408 wtq. After the tune the car made 493 whp and 471 wtq. These are pretty solid numbers for 93-octane in the Texas heat, and Aaron loves it!
