Well i was putting a new tune on my truck i already had the performance tune but i wasnted to change acouple things and redo it but when i go to "install tune" the lil hour glass comes up and nothing else happens it like freezes or something do you think its wiping out the old tune? the truck doesent feel any diff driving it then it did with the tune i had if i cant get this one installed id really like to keep the one i had so im hoping it didnt write over it.
