mileage verification
the vin is on the computer and easily changed.
the mileage isn't on the computer as far as I know, only in the odometer.
i was told that it would be easier to tune if i had a t56 manual pcm, but i was also told i could flash the auto pcm to manual specs but i would have to tow it to the dealer to get it reflashed to a vin specific t56 pcm.. i was hoping to verify the mileage though..
