Ok, this may be a dumb question but I have been considering doing it. I have a 2015 Koup. I am leasing it so that's where im not sure if I should go through with it. Worst case scenario is I get the tune, and fuck up the engine or turbo, then im up shit creek right? Even if I got the original ecu put back in before I took it in, they would know? correct? This may be a rehash of another thread but I don't feel like looking through all them. I have the car for another 2.5 years, and would like a little extra oomph..although I like that TC/SC disable trick, its made the car much quicker and fun. Please give me some opinions. I have the automatic transmission btw, and its completely stock.
