gixxerrider Posted November 28, 2007 Report Share Posted November 28, 2007 I just got my spare PCM from the UPS man. Do I need it reprogramed to my truck vin before I send out for a tune? I have 12589463 in my truck. My spare is 12586242. Quote Link to comment Share on other sites More sharing options...

.justin. Posted May 17, 2009 Report Share Posted May 17, 2009 I got a 03 for my 06 and Zippy tuned it. I think he had a problem at first but dont no how he fixed it For a while there, TIS (GM PCM flash service) would throw a fit when flashing an 03 PCM to an 04 or newer OS. They've since fixed this problem. I'd be willing to be this was your issue. Quote Link to comment Share on other sites More sharing options...
