Hey guys. I'm new to 5.9s... had plenty of 7.3s but new to this game. I just recently bought an 04 with a new motor (Dodge, warranty). The truck runs very good... maybe a bit too good. I'm suspecting the truck might have a chip or tuner installed. It runs it's off, and I have trouble believing this is stock. These are going to be repo/wheel lift trucks for me so I'm not comfortable just leaving any tune in there if I have no idea of what it's doing to EGTs, etc. Where do I start checking? There are no plug in modules underhood. Do Dodges use "chips" similar to Fords also? What about tuners? If it has a tune installed, how do I uninstall if I don't have the tuner?
