I'm just curious about gear changes.
If I were to install a different gear set, say going from 3.73's to 3.31's (or vice versa), for arguments sake. Would I be able to get the dealer to reflash my computer to adjust for the new ratio to correct speedo etc and still maintain warranty?
If I were to do a gear change I'd still want to maintain my warranty on unaffected parts. I plan on zero engine or aftermarket tune mods and don't want to void the warranty.

thanks

Should be able to , just call your local dealer and ask.

What's your reasoning for switching from 3.73-3.31?

It's not a reflash...it's just changing a parameter. Ford dealer can change your setting for this to any gear that was available from the factory as an option for your car.
