Im going to put it back to stock this weekend and see if that helps. I have a bama tune and I keep hearing how bad they can be. I looked at the long term fuel trims and it seems to be pulling too much fuel, ie white spark plugs. So new plugs, oil, stock tune back to factory and see. It makes sense cause no cel on engine or anything related to my issues. Ill let you know what happens, im buying a lund tune after this!!
