Please help. I recentely put JBA longtube headers and a o/r h-pipe on my 2006 gt(with sct tuner). Of course the sensors wouldn't reach so the check engine light is on. So i got extensions for the sensors on the headers. I already had a sct tuner so american muscle sent me a tune that should have lied to the computer so i didn't have to purchase simulators for sensors in the h-pipe but it did not work. I still have the check engine light on and i don't have a clue why. Any one have a solution or idea to fix the problem?
