SCT Tuner Guys??
Just got an SCT tuner with custom tunes from Innovative. I wanted to know first before I plug it in the port, do I need to do anything to save the stock program, or does it do it itself? If I need to save it, then how?? I have the X3.
Also, how do I return it to stock? And when I do, if I have to go to the dealer for repair,I heard they have a way to tell if a programmer was used, even though the truck is returned to the stock program,is that true??
