Question about 2004 Dodge Ram 2500
No, it will not make a difference. I have heard nothing good about the Jet chips. With the mods you have, the factory ECU will work just fine. If you start changing cams, and doing port work, then you may want to get a tunable computer, and have someone with a dyno tune it. Otherwise, you should be fine.
