Try contacting Black06. He's running the 250 tune on a F450. Don't really know what kind of mileage he's getting.

I have a stock F450 with 4.3 gears 12-13 mpg 67-70 mph empty and 8-9 loaded with 14k fifth wheel. I am curious as to what mpg tuned as well.

2008 F450 6.4 diesel dually loaded.

Last F450 with 430 gears we did got a S&B intake 4" Dual Flo Pro and Spartan 275

He said he has never made it from Red Deer Alberta to Valemount B.C. (550KM) before on a tank of fuel and when he got there it said he still had 130KM to empty

Lie O Meter reads 18MPG hauling 2 snowmobiles on a deck

I have a hard time believing those numbers. My towing milage went up from 8.1mpg to 8.8mpg with the 210 tune. I just don't see any 450 with 4.30's going over 15mpg even empty.
I hope it is true for his sake...
