Question for anyone who could help me out. I recently put long tube headers with O/R x pypes and SLP Loudmouths on. After doing this the engine light came on and stayed on. I retuned it with the Diablo and the light went out. Now 2 weeks later the light comes on again. Would any of you guys have insight on this as to how I can fix this problem. I do not believe it is a problem with the sensors and all clamps have been tightned down with impact. Any advise would be greatly appreciated.

you need to turn the rear 02 sensors off using the tuner.
