Sorry but let me get this straight. i am located in canada, and i am interested in this tune. if i purchase it off the site; is it all good to go? or does someone have to program it? i am confused lol
sorry but what is a 'crank re-learn'...dont know anything about cars.
k cool makes sense. one other thing, where is the location of this tune (i.e where do i put this in the car).
one question.. if i get the 91 octane choice, how does that add more MPG? doesn't a higher octane level decrease the mpg?
