Ive had the EGR vents installed almost since the truck was new. Just recently now the drivers side when the window goes up the sensor in the door sends it back down. I have to shut the truck off to send the window up n stay up.
Finally pulled the trigger n installed the Flowmaster dual exhaust { yes I know it's not a true dual exhaust } but any who, n installed my AFE CAI n the sound is great , better throttle response. Does anyone here thinks the on board computer needs to be reflashed cuz of the CAI
Some of these guys are right , not all dealers are the same, I had a GMC dealer who was the worst there is. It maybe you have a lemon which I hope you don't
