Save your money...... :empathy:

:cray: Gas programmers do not do that much for performance nor do they help much with fuel mileage. Some will add some timing and push you to use premium fuel.

If you were going to "go big" you would end up with a cold air intake, ported throttle body, and maybe long tube headers to flow more air with a good tune. But at some point, you have have to add injectors to keep up with fuel and then fuel mileage goes out the door.

If I were in your shoes, I would make sure my tires were at the max recommended pressure and that I was running the stock size tires the truck came with. Is all the maintenance up to date? Have you changed your spark plugs and cleaned your mass air flow sensor recently? That is extremely important, especially if you run an oil based air filter.

While its a lot more money, a new truck might serve you better for your wishes.

I would agree with Brian about the MPG, performance not so much.
We run a 91 octane performance tune in my wife's Mustang and need to run 93 octane (no local 91 octane).
We tried the Street tunes and did not care for them regardless of the octane required for the type of Street tune. The 91 octane Race tune we tried was unmanageable for everyday use. The 91 octane Performance tune makes the car an absolute blast to drive. Of course none of this helps you out with the MPG issue.

The biggest thing you can do to get better mileage is control your right foot. Not being a smart ass, just saying. Programmers on gas trucks are pretty much worthless.

I had an 04 Dodge Hemi 2500 HD. It was a GOOD day to get 12mph with it... consistent was 11.
I tuned it and tuned it, drove lightly... etc... and due to a stupid situation with my now Ex-wife, was driving 140 miles a day. I calculated I burned about $600 a month thanks to her. The MPG tunes basically just lean out your mixture.. which can get bad and cause knock...

The killer you have in your truck is the 4speed auto. Especially if you have the 4:10 gears (it was common on that gen Dodge, to get the 3:73 in the 2500s... and if you do have the 3:73 like I did, the tow rating is only 8800lbs, pathetic for a 2500).

More bad news? Most of the other brand trucks aren't MUCH better (in the HD line anyway)... Don't get me started on the EcoBoost stuff from Ford in the 150. Now, I have a 2012 Chevy Silverado 2500 HD with 4:10 gears Crew Cab but Long bed (so basically the same sized truck as my dodge except 2 feet longer)... it gets about 13.8 mpg on a good day. It has a 6 speed auto, so that's ALL you get. I hear the 5.3 Chevy 1500 does as good as 18mpg, but you'll need a newer one also with 6 speed (I don't think Dodge went to 6 speed autos until 2010ish, and they also finally went to the economy in the HEMI around 2006, where they shut off cylinders going down the highway without a load).

The best investment would be to buy a sub-$2000 beater car with a 4cyl, but it'd take you a while to make up that cost, depending on how much you drive.

If you STILL have to have a truck to drive lots (say you tow a lot)... I'd strongly recommend a 2004-2008 Chevy Duramax 6.6, or the Dodge Cummins 5.9 in the 2004-2007 range with the manual 6 speed. You can expect up to 20mpg with either (I've heard wild stories as much as 24mpg, but that's not common). What is the killer on newer trucks (2011 or newer) is the smog garbage, for the diesels anyway. They are therefore back down in mpg, to 15-17mpg. With the cost of diesel versus gas, it's really a no win with the newer trucks (as far as MPG goes). Of course the newer engines from the big 3 (diesel again) are all pretty reliable again (thank god)... My money is still on the 6.6 from Chevy though. Although I hear the Newer Cummins is also quite good.

I have a bias (truth in information act here) against Dodge, as there was a killer design flaw in the Hemi (not really, it was Dodge cheaping out)... the exhaust manifold bolts were cheap, and broke off in the heads (dissimilar metals), a bear to get out, or stupid expensive (if you pay someone to drill and tap them all out), if you haven't changed them yet in YOURS do it NOW, before they are corroded towards not being able to get them out now (possible)... Also the Dodge had terrible electrical systems, and a major amount of problems with the auto-locking hubs (I got only 10k on a brand new set, and I replaced them like 4 times in 40k miles, 2 each side). They are so bad that a guy I work with gave up on his Dodge 3500 that he went to manual hubs, that have zerks.

Sorry for the book here, but I've done a LOT of research on trucks... as we are HARD on our trucks (towing lots), and several of us (all field trialers) have experienced what happens when your rig isn't reliable (nothing like getting stranded on the side of the road towing horses, NOW WHAT? I'll answer, Rider insurance, those folks can be a god send if you don't have a friend with a similar sized tow rig).

Anyway, most of our field-trialer friends have gone Chevy/Gm, and haven't looked back. They all stink really in MPG.

I just found myself in a bind and had to buy a 'new'/ used vehicle in November. I previously had a 2002 Jeep Grand Cherokee Limited. 160K It just seized up! I suspect that it wasn't totally topped off with oil at the last change, but can't prove anything! It only delivered 14 MPG with a 4.7 V-8. Just bought a 2006 Grand Limited w/72K. Ran to NYC and Delaware Last week and it came in at 16.5-17MPG. It's a 5.7 Hemi. So far I'm pleased. I knew what I was getting into, and it's no Prius .....mileage wise. ~Scotty~

Honesty the best factory option with a warranty is Toyota. Their 5.7 with the TRD supercharger will be 400-500hp and the couple that I do know see a mpg improvement as well. A tuner is a waste of money IMO.
