im getting some 33's to go along with my body lift, and im just curious if theres a way to correct the speedometer with the xcal.

 

When you fill out teh form for the Xcal, I believe Doug asks you about this, as well as your gear ratio etc.

 

lol i already bought it, stating my previous tire size. i was just curious if there was any way to go in and change it myself with the tuner.

 

in general terms you want to reload the tune but pick to customize it. When it gets to revs per mile, that is what you want to change. You can go to online tire websites to see what the revs per mile is for 33's. I think it is 630.

 

what he said lol

very easy to do too
