How many MPG's do you get?

ONLY 6.4s PLEASE!! I want to see what people are getting for fuel mileage. City and Highway. Lifted or not stock or high performance. Sorry I don't no how to set up a poll.

I average between 17-20. I had my truck tuned, but it made absolutely no difference so I took the tuner off -- all I have it on there for is watching temperatures. (It was not a very good product, I won't vendor bash though, it was the only one available when I bought it).

20 usually happens with the right weather, about 75-80 degrees and low humidity.

In the dead heat of summer, 95 degrees, 60 percent humidity, with the AC on, luggage, me, the wife, and the hound in the truck at 70mph I got 17.8mpg hand calculated.

I have noticed fuel quality plays a big factor in mileage. If I run the good Sunoco Gold fuel, I notice it's good for almost 1mpg increase.

My truck is a Job 3 2008 F-350 Off Road, 3.73, 4x4, 275/70R18. It has the latest -CG level calibration in it from Ford.

chit hillbilly, If I woulda got anywhere close to that stock I would've left mine stock too.

I averaged 15.6 last tank mixed driving with the Spartan 250 tune. Even had a couple of kills on there. Managed 421 miles with 30 left to E. My first 400 mile tank of fuel by the way. Each tank keeps getting better which I attribute to break in of the engine and the ECU and Spartan working together better.

I get around 21mpg on the highway with a PHP chip set on 80 daily, 6637 filter, 5" exhaust and i get around 18 in town with the same set up

Before the chip i got 18-19 highway and 15 city and i had the 6637 filter and the exxhaust with this as well.

If your looking for a chip to increase your fuel milage, Id definetly have to say go with PHP. Bill's tunes are awesome and I couldnt be happier.

Also your getting used of the programmer and not wanting to stab on the pedal as much.

Who makes a PHP tuner? Are you talking about a 6.4ltr.?

Fellas, not trying to be one of the 6.4 jerks that thread hog but he posted this in the 6.4 section so I think he's trying to get mpg on the 6.4. We all agree the 7.3 and 6.0 get better mpg. Just saying so his thread doesn't get wrong info ya know.

[benjamin24]

choupique, you're absolutely right. First couple tanks I was racing anything that wanted some and puffing smoke at anyone on my arse to close LOL
