Hi guys I have talked to 3 dealers to get my ecu reflashed to 06 map(is 03 f7 EFI) and all say that Cat won't do it. The one dealer is a performance oriented dealer and said that program hasn't been avaliably for 3 years. Is this only available state side and not in Canada? Is there a # I can call in the States or a dealer # that can do it? Any help would be appricaited !
