I have a 00' Durango with the 4.7 fully loaded and 135k miles. I've added the following, Roar intake, BBK 70mm TB, Jet thermostat, Superchips program (agressive mode), 3" cat back exhaust with a magnaflo muffler. I've owned the D since new and love it, just trying to figure out how to make is a bit more fun to drive. She's got the Shackle / torsion lift and new BFG's (32 x 11.5") TA/KO's on it as well. No leaks, runs like a champ and looks new inside and out.

My question is, is there another bolt on that will give this beast more nuts? Gas milage is not an issue (I rarely drive it) and am just looking for the opportunity to 4 wheel ocassionaly with more than enough power and maybe take a mustang light to light? Can it be done? No budget for a supercharger, not a big fan of gearing changes but have I covered all bases? Reliability is critical.

Thanks

 

Do a search on viper fan. that will free up some power.
