I have those same tail lights on the same rig. Do they send you a "tail light failure" notification on the information center? If so, have you figured out a way to stop that? Did a particular resistor work?
not yet im not done yet, still plan to do cam, rockers, and transmission witih high stall torque converter, then SCT Tune, ill do that after all that :). For now before the tune and cam, i gained some power on higher rpms, but lost low end torque so its pretty even in acceleration 0-60 compared to stock... but like i said im not done yet. I will make another vid once im done with all mods... ;)
