If you can force yourself to keep you boost under 12 psi (8-10 would be better), you will see a marked improvement in your mileage. I know that it is hard to do. I have tried it and have yet to make it through a full tank before I get the lead foot. On the tanks I almost made it, I saw at least 2 mpg gain. Give it a try.

Why a DP tuner?? What do you mean by better intake and exhaust???

And What the h*ll is a EPBV???

Also I just changed my fuel filter and oil right after Christmas, and just check to make sure that the drain valve is NOT leaking.

I have hiway tires on the truck as it sees way more on road than off, also it is stock high, no lift here. I try not to hit the accelarator any more than I need to. I set my cruise allot.
The one thing that I would like to get a bed cover as soon a money will let me.

Thanks guys for all the suggestions, please if you have anything else... let her rip...

Also what does the small can on the back of the turbo, that has a red vac line going to it do??? And how do you know if it is working???

Doc.

depending on which rear end gear you have the low 20 mpg may not be attainable. My truck has a 4.10 and I am lucky to see 16 after a LONG empty run on the interstate.
You can also consider a Gear Vendors (or equivalent) under / overdrive unit. It is a unit that is installed behind your tranny (with a shortened driveshaft) and splits the gears basically to lower your RPM's at any given speed.

I have 3.73 gears in the truck, and the gear vendor would be nice but out of my budget at this point.

Here you go David, there was a write up about him in Diesel Power. http://www.dieselpowermag.com/features/ford/0612dp_2000_ford_f350_mileage/index.html

He is a member here, but is usually found on PSN.

here is a pic of his truck

Thanks Brandon!

I just had to check it out. I got 24mpg in my truck once. No A/C, ~1950rpm, and a really good wind pushing me, lol.

Things to consider on his truck that really make it a commuter:
3.08 ring-and-pinion
235/85R16 rear tires & 225/75R16 front tires
a custom-burned chip that decreases fueling and advances injection timing under 2,000 rpm

What really made me laugh in the last paragraph:

"Dave has already managed to improve the fuel economy to 26 mpg (up from the stock 20 mpg)"

the 6637 is a dead give away, lol. i like the custom cover. i'd bet that custom chip is a DP too.

He did a great job and a 6mpg increase is awesome.

You said to use a DP tuner, why??? Is it better than the others on the market or is this the one that you use???

Also what HP setting are you using, or what would you suggest I use???

I have a 02' E350 7.3PS Van that I recently bought to haul my dirtbike to the races. It was an old electrician van w/ ladder racks, cage, & tool bins inside. I took the rack off, all the bins out, so I could haul 2 bikes. It has 175K on it and is totally stock and I have been getting around 18-19mpg. I was considering a chip, exhaust, intake, to gain some power but I don't want to lose any mileage. I think w/ the chips it's hard to gain mileage when your adding more fuel to the motor.

What kind of mileage did you get before the mods?

I wish I could post my excel spreadsheet of my mileage over the last 2.5 years. Yes, I am a loser, but it really can show you some things. You can see the downturn w ULSD, Winter Blend, New DP Tuner (That is not the tuners fault. Black Smoke!!! ) It averaged 15.7 in the end w 10.99 the lowest pulling gn and 21 on 55 mph roads.
Nobody has mentioned intanks or 203* stat??? Wouldn't eliminating air in the system be more efficent? Isn't running the engine warmer better for efficent combustion?
I am struggling with my physics. Why are little tires better? Wouldn't slightly larger tires push the truck farther for one turn of the motor?

the intanks are definitely worth doing, but I didn't notice any mpg gains.

the 203 thermostat has been debated quite a bit. Gene posted a pretty detailed thread about the pros and cons. It just really depends on where you live. Its pretty hot where I live and I don't think I would really benefit from the 203.
