after putting my lift and tires on this weekend, of course my speedometer is off. could i use someones programmer to recalibrate mine? i have the edge/***. and it shows correct speed but i would like to set the stock one. if i could do this i would pay shipping back and forth so i could recalibrate mine. i'm happy with my edge don't want anything else right now.:)

I dont think that would work. I know the Bully Dog wont be able to for sure, and im almost positive the same goes for all the others. The programmers marry to the vin# on the truck its installed to. But Superlift makes a chip specially for spedo tuning. It runs under $200. That is your best bet as far as I know. Good luck
