Power Wagon Registry

I recently acquired my 2005 PW and took it off-road park already and it did great and better than I could have hoped for.

Downside is that over the last 1000 miles I keep seeing just 12~12.5MPG on the overhead module.

My thinking is simple. Perhaps increasing my MPG to 13~15 MPG. Can it be possible with a simple Diablo custom tuner along with K&N filter and picking up a muffler to weld in place of stock one too.

Wishful thinking on my end?

I know at least it would sound cooler

I would recommend not getting a k&n filter, a dry element filter will perform just as well and protect your engine better. AFE makes a really good filter that is serviceable and will last. Between an intake catback and tune I'm thinking you can pick up 1-2 mpg or a little better no problem. When I first got my truck it had an intake muffler stock tune and tires and I could do 15 highway and 12 city. You just have to not hoon around lol

Well, I can keep it 65 MPH on Freeway and go very easy on the streets and yet my MPG's hoover at the same low 12's MPG.

I definitely will do the tune and the weld in place flowmaster.

Best i've ever seen is a little over 14.... unloaded, down the mountain, with a tailwind.

13's are common with a light load, 65 in the mountains.
12's average (sled+gear, highway).
8-10 with my trailer (steel 2-place enclosed, +sled/gear).

K&N intake, exhaust's getting reworked very soon (terribad flowmaster dual on there, going to a single 3" magnaflow and doing it right). No programmer (yet).

12-12.5 average sounds about right. i had an 05' pw with headers, catback, and cold air. not worth the money for the minimal gain in mpg, especially if you acquire a lead foot taste. had a super chips tuner on it too and it wasn't worth it either.

I would be thrilled with 12mpg. My '05 QC Auto has given me 9.7 (uncorrected) and about 10.0 (corrected for three different tire sizes) over its 10-year life. I have an Injen CAI, Banks Monster catback with new Y-pipe, and recently added the Edge Evo 87 Econo tune. I am now at 9.2 (uncorrected) since adding the econo tune. The only time I ever got 12mpg on this truck was the weekend I bought it and drove 400 miles home at low speeds to break it in. Count your blessings, because you won't be counting your money.

Sweet lord that's abysmal mileage! Wow i didn't realize how good I have it

I get 12 mpg towing 13k lbs!

I thought bad gas mileage came standard on power wagons lol, anyway I had an Airaid intake tube on my old 05 pw and I got 12 to 12.5 from 11 to 11.5 with the factory setup, don't really know much about the programmers or how much they will help, I always heard to stay away from them. Just remember you got 456 gears in it not really geared for good gas mileage, geared for kicking a$$ lol

Enough outta you, mister...

Run, do not walk away from using a K&N. That is the single worst thing you can do to your truck unless you like passing 20X the dirt a paper filter does...

Mileage... buy a newer one, mine gets 15-17.

I was somewhere around 11mpg average bone stock, now with stock intake, stock exhaust, Diablo and 37"s I hover right at 14mpg daily driving. The bigger tires helped the "highway" gear, easily get 15-16 traveling. The low gears and small tires is the most hurtful on the miles per gallon.

Man, how are you guys getting this kind of mileage? This is my around town average....interstate is about 8.5

got a couple thousand lbs on the hook? :dunno: Does seem like something's wrong if you're not getting at least double-digits with unloaded/around-town driving. Everything getting up to temp (Engine/coolant, transmission)?

Buddy and I, my trailer, two sleds, fuel/gear, tools/parts for a week of riding...


...see those flags? 30-40m/h headwind for most of the trek across Wyoming...

My old '06 would never hit double digits...

I know mine does not have the MDS so thats not it. The Yokos I'm running are fairly light and definitely more aerodynamic than a knobby, plus I have a top that's probably good for close to 1mpg on the hwy. I'll be pulling a tractor around with me this weekend and I'm sure it'll drop to 8 or 9 but we'll see.

I cant thank you all enough for your input.

I honestly thought I could improve the MPG some...lol

Well, since I have now 35's that measure up to 34in true height on truck I will check GPS while driving and would only get the tuner if the speedo is off.

Thanks again,
bigC



trying to stretch to make sure no rubbing.

It's a good chance it's spot on now, mine speedo was a little over with stock tires and almost dead on the money with 35's. a 34" would have put it right on.
