I'm thinking of buying a rig. It appeares to have a performance program on it but no clue of what kind. Is there a way to return this back to stock? Will un hooking the batteries whipe this out and return it to stock? Or can I take it to a dealer and have them re fash the computer? If I buy this I would like to return it to stock so I can put a sct xcal on it. It is a 06 f350 dually. Thanks in advance for the help.
