noob tire size question
hey guys i just have my truck in the shop right now getting a lift and 35" tires installed. How do I go about changing the tire size? Do I have to do this for each level?
I realize there is an option " Do you want to make a custom program? (yes)/(no)"
do I have to use this option? Im just afraid of it wiping my custom tunes if
I click yes.
happy thanksgiving.
