Some dealers act all crazy about it like your trying to steal a car or something. So my understanding is that the best thing to do is get a used one with the correct service number, then buy the access from HPTuners for that VIN. Then download the correct program for your application and write it to the ECM. The VIN won't match your VIN, but that won't matter. At least that is the way I understand stand it.
