BTW.....I ressemble all those remarks! LOL


Op: When I researched it, they were just coming out with a program for the 2007-2010 models. My poor little 2006 was left out to dry, so I said screw it. I did by the Hypertech speedo calibrator and still have it installed. It corrected my speedo up to 1-2 mph difference, I can live with that. You can also recalibrate for gear swaps but not rev changes. I will try to find my old thread and link it here....
