My 2016 Championship Edition ATS-V couldn’t have been tuned more perfectly. Even with the extreme temps of the UAE, my car makes 522 whp on stock everything (only cat delete) with Scott’s tune, and I’m not even close to knock threshold. Ran it for a year so far with no issues. Scott was very helpful with all the steps and guidance along the way and made sure that my engine remains healthy and usable daily while delivering a LOT of power. Highly recommended.
