Ave 14 mpg
I just took a 400 mile trip, and running an average of 75 mph @ 2300rpm or so, I average 14.0. I honestly expected more. The pos is a 99 cc drw with 373, and 58,000. Is this normal? Thanks

If you drop down to 70 MPG which should be about 2000 RPM with your gearing I would expect that you would pick up around 2 MPG. 2000 RPM seens to be sort of a magic number with these engines and above that it uses a lot more fuel. By the way, you do have a CC dually!

If I keep mine @ or below 2000, I can get as high as 16 but not any higher. I think this is pretty good considering fact it is a CC 1 ton. I have tried the predator economy tune and the SCMT tuner as well. No improvement. I have heard people getting a lot worse so I don't complain.

I drive a few states and I average 85 mph on the interstate. I run about 2250 -2300 rpm, 3.73 gears, and I run the Diablo chip in the 54hp mode.
I have the AIS intake, 4" exhaust and I average 16.5 - 17 mpg. I have never driven my PSD below 2000 rpm except during break in. Mileage has always been between 16 - 17. But I have a 2wd too.

Just got back from a fishing trip this weekend and put on just over 400 miles packing a 8' camper pulling a utility trailer with a aluminium boat and gear. Got 16.5 mpg cruising at 1800 rpm.

Just returned from a 1,230 mi. Yosemite/Sequoia trip. Drove 70mph at 1950 rpm and then running up and down those steep hills sightseeing and stuff. Ended up with 16.1 mpg with about 1500 lbs in bed/truck combined. Better than the 12 mpg I got with my ole F-onefitty 302.
