Programmer, Intake and exhaust, basically your bolt ons.
These are the same motors that are in the Charger R/T so they are detuned like crazy, only 360hp. You can't expect something crazy out of these Durango's as they are heavy, have some body roll (even in the R/T) and a ton of torque management. lol
Now if you rally want to get up and go you can go forced induction, but your tranny will be toast so plan for a converter and a good tune on top of it all.
