2003 3.9 with posi, tow pkg, HD group, club Cab, Ext cab. I use it for work, hwy/town driving and get a little over 16mpg. Just put in replacement K&N. Going to do one tank and check milage. Next is Flowmaster [40 series]. I'd like to do something with the ignition. Jet performance module?, MSD6AL?. Anybody have a thought on that? One other thing, does Dodge offer any performance support for the 3.9?

2002 SXT 3.9 Auto 4x4
Stock I was getting 13-15mpg, and I have a heavy foot most of the time. I added the following...
Intense Performance Stage II Intake
Dynomax #17748 Super Turbo muffler
Autolite Platinum 3923 plugs (AP3923)
Now I am getting 16-17.5 mpg on a normal basis. My best, and this is when I was driving without my foot in it a lot just to see, I got 18.1 mpg.
I have heard mostly negatives on the performance modules...mainly that they do not do as stated.
Dodge does not have many performance mods, if any, for the newer 3.9s...there are a ton of other places though...search the net. A good place for info is www.speedtweaks.net, they no longer have a full site running but they have kept a list of performance FAQs.

I find it quite sad that people in here have their trucks with less than 50,000 miles on it and they get only 15 or 16 miles a gallon, i just turned 162,000 and am still getting near 20 miles a gallon every tank. and all i have added is a vortex exhaust system and the K&N injection kit. It seems to me that the newer engines get far less gas mileage than the older ones.

I have an 2001. I was not impressed with 16 mpg either. I thought a V6 would do better. I put in the K&N, no help. Then Gibson hiflow catback, jet stage 2 chip, smaller crank pulley, low temp stat, and my own custom ram air intake. I now get over 20 mpg.
I am looking for headers and possibly hi flow cat.

I helped by brother with his 89 Dak 3.9L get 36 mpg hwy and low 20's in the city (CDN gallon ~3.8L). Cleaned up the tbi big time and then retrofit a 1990 air cleaner off a small block chevy w/ K&N element and inverted the lid.
It rocks!!!

I just bought a 2001 DDkta, I must tell you it burns gas a lot. I don't know what to do. Has anyone heard about the Balljoint problem on all the Dodge Dakotas and Durangos? It's a shame, you spent so much money on a car to find out all sorts of related problems.

I get 19mpg consistently in the city and about 23mpg on the freeway, if I ever drive on it. No A/C of course. That makes a big diff.
2002 SXT RC
K&N CAI, Gibson single side, 180 T-stat, 360 Air Intakez Air Hat, 3923's, MSD, and hopefully more to come.
