You don't have a 26 gallon tank, you have a 29 gallon tank. 320 miles on 25-26 gallons isn't that bad actually with the ULSD... I'm only getting 13mpg right now with my driving habits and 33" tires. Best way to get good fuel mileage is to keep an egg under the gas pedal and get an economy tune from DPTuner.

yeah ive heard alot of people say keep it below 2k thats what i try to do , but i think im going to put the stock wheels with the 285s back on ,the big wheels are just costing me more money

So what milage could i expect with a 7.3L with 6" lift and 37" tires

I run a 4" lift with 35's. I know somebody is going to claim bs, but I got 18.2 mpg coming from Nashville TN to Raleigh NC running 72 mph @ 1900rpms. My calculations were made with my GPS reading my distance traveled and my speed. I also run DP's econo tune and was actually running my 18k with it this time. Best I can do with just the econo tune is 17.0

well you can't have it all, you've either gotta give up the donut tires for less mileage or keep the donuts and get the good mileage

I have an 8" lift with 39 " tires and get about 10 to 12 miles to a gallon.

If you haven't corrected the speedo then you are getting more miles per tank than it shows. I have 3:73 gears a superchip flashpaq intake, exhaust and get about 19 mpg and thats not all at 2K!!

well i think alot of it has to do with the tuner i have quadzilla im not at all happy with it , whats the dp tuner i see alot of people have it and are very happy with it , where can i get one , i have an 01 7.3l with tuner 4inch exaust , intake and voodad mod and i got walked on by my friends 06 6.ol is this what i can expect out of th 7.3
