thanks, that helps ALOT. so you can only have 3 tunes on the programmer at once? say i get 1 custom tune, when i remove one of the other tunes and put in the custom tune, will i ever be able to get the canned tune back if need be? how can i turn it back to stock settings for when i go to the dealership for warrenty work? does the canned tunes improve fuel economy? if i get a custom tune for a catback exhaust and a cold air intake, then later on down the road i get bigger than stock tires. will i be able to use that same custom tune and just change the tire size on the programmer or will i have to buy a new tune? do tunes cost more if you buy them AFTER you buy the tuner rather than the same time you buy the tuner? cuz ik that some other companies charge like $30 for a tune the same time you buy a programmer and double that after the fact. how does the programmer mount in the truck? suction cup to the window or do i buy some kind of dash mounted system?
