Or just trade it and get a Chevy! My 1/2 ton 1988 4x4 with a tonneau cover gets 20mpg and that is with 373 gears and 32x11.5x15 BFG MT's on it. Yes that is mainly all hiway miles 120+ a day. As far as pulling I have 1 ton overloads on it, cam, roller rockers 700r4 trany and it will pull anything an mid 90's diesel will..... just saying....wish I could say the same about my newer dodge.
almost forgot the 20mpg is at 73 mph.

I see everybody else getting like 12-13 and I just don't understand... I would be happy with 10 MPG lol. I have the 5.9 magnum, and a host of stuff done to it... Magnaflow cat, flowmaster super 40 with duel exit, pacesetter headers, Accell Cap Rotor Plugs 8000 Wires and Coil, Superchips programmer, 265/70/17 street tires, stock 3.55 front & rear end, Reman stock heads, New plenum gasket, Spectre CAI, and I think that's it for the info... So if anybody has any ideas.... THEY WOULD BE GREATLY WELCOMED!!!!! Otherwise, I'm about to give up and trade it in for something else.
Everything you've listed should increase mileage with the exception of the chip. I am running a Turbo City intake, custom exhaust with headers, high flow cat (now blown ), and the factory performance computer. The only downside to that is I have to run premium fuel. But I am getting 14 and that's running 3.55's and 35" BFG's at 6500ft altitude.

Need to grab cooler air from outside of the engine bay.
I've tried all different kinds of plugs and find the stock ones run best. Can't explain it, but these magnum engines love 'em.

So that's a heads up for others to try. The other thing is we have gone from low 100 degree temps to mid to low 80's now. The next strep I'm going to take is changing the diff fluids and transfer case fluid. I want to do the trans but I don't want to mess up a working tranny with the way these dodges are lol. So... What fluids do you all suggest I use in the diff's and trans case????
The fuel we get here in Colorado, in a word, SUCKS!!! I run Shell or Safeway and that seems to get me the best results.

The next step I plan on doing is changing all the fluids and switching them to synthetic, But I'm not sure what to run. I have been thinking of using Royal Purple, but i don't know if I want to spend the money on it yet or not. I haven't herd enough good or bad to decided, well besides the guys on tv who get paid to use it, of course they are not going to talk bad about it.
Royal Purple is good, but too expensive for me. I'm running Mobil 1 10/30 and am happy. When I rebuild my motor, I may switch to RP, but for now Mobil is cheaper and get's the job done.

BTW...newbie and glad to be here.

Gen1dak will become famous soon enough

In an admittedly quick glance at the OP, I see several add-ons, but what about the basics? New O2 sensors, new MAP sensor? Timing chain tensioners can only do so much and wear out too so how about a new timing chain/ gear set?
The stock 5.9 cam is already pretty lazy, so once things get slack it just gets worse, besides, you need to shore up your foundation to make the most of the add-on mods. Also, how many miles on that cat? Free-flowing exhaust is useless with a clogged cat.

I agree you need a good running motor before moving on to mods, but I wouldn't start changing things without knowing they are bad, might as well just throw handfuls of cash at the engine bay. A bad sensor 9 times out of 10 will trigger a light, same with the cat. Timing chain or tensioner going bad should be noisy.

Breathing in and out is good enough for me.
