I still cant get the STG II tune to take on my 07 redline. I have had the dealership flash it for the past two days and it still wont take. I have a makeshift tune via HPT that I adjusted the stock tune to match an 07 cobalt STGII. Does anyone have an 07 Redline STGII file? Or can someone lead me in the right direction please I am really SOL. I would really appreciate the help. Thanks.
