Default Re: No Calibration Needed!

Aren't the speedometer for the HUMMER's now electronic, meaning there are no longer cables? And the speed is now computed throught the PCM? If this is correct then there is the possibility that the PCM may have enough variance input into it that it recalculates automatically. Have you paced the truck with another vehicle to see if the speedometer is wrong????
