OK a buddy of mine just bought a early 04 with a 5.9 auto. And another buddy of mine has a 07 with a 5.9 and a auto and i think he has a bully dog programmer in it. Both those guys say they can put the programmer from the 07 in the early 04 truck. Can they do that without messing something up?? When i was looking around for a programmer it listed the 03's and early 04's as 1 programmer and the 04.5+ as a differnt one. Was i wrong telling them this or not? Or does it depend on what bully dog he has?
