Hey all, I just received my ProFlash Programmer in the mail yesterday...I'm having a problem and I thought somebody with it might be able to help...I bought it because I bought a new set of larger wheels and tires. I measured the wheel & tire combo from bottom to top as it said in the manual and entered that number. However when I drove it instead of the speedometer reading a little high, the speedometer read WAY high...
Is there some sort of ratio you have to use for comparing the stock wheels to the new wheels? My new wheel measured at 31.5" whereas I believe according to the ProFlash, the stock setting is set to something in the high 20's (which I know is wrong)? Can anybody help?
Thanks!
