I have a 17 Limited 2wd with 315 gears, no limited slip. If I were to change to 373 with a locker or LS differential, could Ford simply program the truck to recognize the change or would I have to go with a tuner and void the warranty? I pull a couple different boats in the Ozark mountains and so far havent had any issues with the 4500 lb boat but havent yet hooked up to the 8k lb boat.
