: Which tuner or programmer to BUY? lierman44 03-22-2009, 01:40 PM I have an '04 GMC 2500HD 6.6 LB7 Duramax. I want to buy a power chip, but have no idea which one. I want a little more horsepower and maybe better mpg. I don't really want to have to upgrade any other components(ie. exhaust, air intake, etc.), at least not right now. What do I buy? rdeterman 03-22-2009, 06:08 PM Ppe... 110crash 03-22-2009, 07:17 PM Ppe... X infinity! AlligatorPerformance 03-22-2009, 07:36 PM As stated above, the PPE is the best canned tuner for the Dmax. It adjusts tire size, reads DTC's, had transmission re-learn, reads balance rates, and is the smoothest shifting hand held you can get. I have them available, let me know if I can help. Chad | ||
