i just put a quad tow chip in my 04.5 did not see any chage at all the red light came on on the box pickup runs fine but no change. put one on wifes pickup a while back and saw improvement right off hers has a 6 speed mine is an auto is that the problem

 

I thought there was supposed to be a green light on when it was working correctly? Have you tried to contact Quadzilla?

Other than that, I can't be of much help.
