Help with Speedometer Calibration
I have a 96 vette with a 4.10 rear end and 4.09 speedometer gears and I can't get the speedometer to be accurate. It seems the faster I go the worse it gets. I have the Hypertech programmer but know what to set the speedo for.
Will it be possible to change the tire diameter to get the speedo more accurate or I am never going to get this right?
