i have been looking at getting the x-cal 2 for my 4.0l sohc and i had a question about one part. where it ask you for you tire size.. i have 245/75R16's right now. but if i plan on lifting my ranger in the future will i have to get a new tuner since it will programmed with 245/75's? thanks in advance
nah form what i understand about our xcals, is you really only need to go to a tuners shop if you get major engine work dont (ie supercharger, turbo, injectors) everything else (tire size, gears, timing, etc.) can be done yourself through the menu.
