mpg update with spartan 275

Went on a 1000 mile trip and with the 275 here are calculated results
65-70 mph 19 mpg
75-80 mph 17.5 mpg
55-60 mph 23.1

Now this is in canadian gallons 1 canadian gallon = 1.2 u.s gal
08 f350 srw crewcab unloaded with 32 in tires
Speed really kills mpg on these things as aerodynamics are terrible.

Those are some pretty good numbers I will admit. I get 18-19 in the 250 tune running 80 mph (Colorado interstate speed limits are 75 MPH!!!) I hear what your saying about speed though. If I would just slow down I could break into the 20's, but then I would be getting passed on the interstate all day. I just cant let that happen.
