Sooooo onto my next debacle. My 07 GT500 was bought with, smaller pulley, CAI and Longtubes installed. Also came with a handheld that I was told contains a VMP tune which is on the car. The issue I am having is that the engine light keeps coming on indicating bank 1-2 O2 sensors fault. The sensors are new and the wiring is good. Anyway that I can tell what the vmp tune contained and if it was tuned for the longtubes?
