Just do it! I am one of the most nit picky people when it comes to my car. Scott ensured that everything was 110% before finalizing the tune. Now my car is much more powerful and responsive than stock, and it has almost ZERO knock. The stock tune has so much knock in comparison. 10/10 would recommend to anyone that wants to tune their ATS-V. Scott’s competition can’t even complete with the service Scott provides.
