Hey there, just got a 2003 dodge ram 4x4 offroad edition with 6" lift on 35"s and 60k miles on engine. And 3.92 gears all around. I wanna get some better power and mpg possibly. So what chip would be best? Or none at all? Also it has full flow master system with flow master cat. Thanks yall

 

Superchips. Hemi or 4.7 you will see gains. Especially if its auto and you get the trans tune.

 

Nvm just saw the 03, no trans tune for you.

 

Is there a specific superchip that'd be good for it?

 

Flashpaq 3865 is the typical go-to.... You can get a Cortex, but it's an extra $100 for a limited transmission warranty.

 

You can probably find one cheaper in either the for sale section of this forum, or on craigslist. If you go the craigslist route, make sure they de-tuned their truck first. Id even go as far as plugging it in to be sure.

 

If you want more power and MPG after the tuner get rid of that Flowmaster!

 

For an 03, the SC3865 is a waste of funds because the ONLY thing it offers over the SC3815 is trans tunes which an 03 cannot utilize.

 

Found a deal on a superchip 3714 for 03 dodge hemi... Anyone used one before?

 

Uhh I'm pretty sure thats not a model for our trucks. I would stay away from it. You want a 3815
