fuel mileage

hi, I've got a 99 F350 Crew Cab w/ the 7.3L PowerStroke, and I get around 15 mpg unloaded with it. For those of you with similar trucks, what kind of mileage do you get? I looked on www.fueleconomy.gov, and a couple other sites, but my truck isn't listed, I think cause it's too big.

There aren't mileage ratings for vehicles with GVW's over 8600 (might be slightly higher or lower) but basically any 3/4 ton or heavier truck isn't required to have mileage ratings.

my 5.4 gets 10-11...no matter what! it got that when it was stock, and then i put a k&n a/f, and a high flow cat with 4" magnaflow muffler side exit exhaust and it still gets 10-11 mpg. doesn't matter if im easy on it or hard on it. i just got a superchips power programmer and i am still on the first tank so we'll see what that does. i have the setting on performance.
