[QUOTE="Creedence85, post: 281313, member: 4346"] Any update on this? I assume you've cleared the codes and they come back? You don't need a tune with an intake and a cat back or manifold back exhaust, and those mods likely won't cause those codes. It sounds to me like it might be bad cats, no cats, a bad 02 sensor, or missing 02 sensors from the catayist codes and the lean fuel trim codes, so that's a good place to start. The only exhaust you need a tune for is headers, and the car should run just fine on the stock tune if you have headers, it just won't get the power increase. [/QUOTE]
