Has anyone run into warranty issues while using FORScan? I'm planning to install a 3:55 diff, but since I run a 6r80 I would have to change some values for the new gear ratio. I've been avoiding tuning my car because I bought an extended warranty, would changing the gear ratio with FORScan basically be the same as tuning my car to a dealer, in that they could potentially void any repairs to my engine, transmission, etc.
