part # for the 99-08 Jeep gas vehicles is 3875. the best price i have found so far is on www.airram.com
^Yeah thats a spanking deal, 315 shipped.
I could tell a huge difference even before my newest mods! Def. 20 hp stronger....better shift points, ran cooler etc. I can really tell the difference with the AC on. the truck PULLS much harder and gets to the redline faster.

I have to get my hands on one one of these days...would like to see what the H.O acts like after it.... 
I had a TSB performed on my Jeep and superchips had a new program for mine the next business morning.
you can also change 1-2 WOT throttle shift points and speed limiter with the superchips

how come airram only has stuff for the 4.7?
he doesnt dude.....look at his whole site. But he does have mnore stuff for the 4.7 and he is about the only vendor that does. Everyone else is the 5.7 or 6.1

It's supply and demand,most people have 4.7L or Hemi's(5.7 or 6.1)and it's easier to stock parts for people that will by them.Although the 4.0 is a famous motor people don't uselly build them to go fast so the demand is down and he doesn't need to supply.He does have some odds and ends for the 3.7 and he is getting more because the demand is there!

The Jeep tuner will work on the 4.0's too....they tune all WJ engines...so if you wanted to go with one Dylan...you'll be fine...

I will be filling up tomorrow at some point I'm sure... EVIC is reading 25 miles to empty, and I've put 285 miles on this tank so far. I'm guessing somewhere around 17 MPG for this tank, which is in line with what I got pre-superchips, however I've been driving a bit harder than normal this tank.
I'm more interested to see what I get on the highway now with the 91 tune but MDS disabled.

Geez I wish I got allowance I am going to get a job after summer school though.
LOL...allowance FTW! You are lucky though....I never had a car till I went to college. It was a 1984 Chrysler Laser......and if it had a fluid...it leaked. I drove it from my hometown in KY to tuscaloosa, AL several times though....filling with fluids on the way there.....LOL
