Hey guys, I need some help tuning my 08 Gt. I have a SCT SF3 tuner and just put on hooker full length headers and x pipe with out cats. I cant get my tuner to put me to the page where I can insert my afermarket upgrades so that it can tell my cars computer what to tune to. Its running like crap now but, I also put on Steeda's underdrive pullys. Prior to this, about 2 months ago I instaled Steeda's intake and elbow and the tuner worked just fine for me. Do I need to set it back to stock so that I can start all over? Help please!
