I just had 3.73 gears installed in my 02 GT so now my MPH is off anywhere from 5-15 depending on how fast I'm going. I didn't want to spend another 100 just for a speedcal. I figured I would go ahead and put that 100 toward a programmer (chip). Could someone please recommend a good programmer. My only mods are gears, KN cold air intake, flowmaster (dumped). I do plan on underdrive pulleys in the next couple of weeks and maybe a prochamber. Should I wait to on the programmer until these other mods are installed or does it matter? I'm not expecting anything crazy out of this mod, just a few horses. Does anyone have any dyno numbers after reprogramming. Thanks for taking the time to read this.
