The only other item I have put on is a MAC cold air kit. Other than that everything is stock. Weight or truck & trailer is about 17,500#.I also installed the 3 guage piller pod.
Just installed the superchip-no matter what mode we set it on,my fuel milage went from 13.9 to 9.9 while towing my 5th wheel trailer..is this normal? Please respond...I'm at a loss.
