I have an SCT X3 for my 07 Powerstroke, and love it! Question is, does anyone know if I can use it to only change the tire size calibration on my friends truck? (while leaving my tunes and the one in the truck alone) He drives an 01 F250 Triton V10. I just don't want to mess anything up. Thanks!

I don't think you can, the SCT should be customized to YOUR truck only. That may be different if you have canned tunes, but I'm no expert :dunno:

No. You would have to return your truck to stock to be able to use it on his. Then you would have to return his to stock to be able to return it back to your truck. So you would be returning any change in tire size back to what was programmed into his truck by the factory anyway.

No. The tire size thing on the SCT is just for the transmission anyway, it doesn't calibrate your speedometer for larger tires.
