Either way that is a way heavy load to be hauling with those tunes on. |
Well this trailer is just under 8000 lbs light, But I Usually Haul around 15000 lbs but I Have Pulled some Illiagal sh*t and Hauled A Couple loads over 28000 lbs and Idk Ive put 100000 Miles on this truck 85% of the time with my triple axle trailer and the tranny still shifts like the day I bought it. Its a work horse:tu: but FYI I am going to get the SCT tuner cuz I do like GOGO diesel and RCDs tunes for them :yeah:
|
So you're saying you pull 8-15k at 75 MPH and get 14MPG correct?
|
Thats Correct Any thing over 15000 Ilbs is a little heavy to be traveling 75mph i usually keep it around 65 then but any thing under that after getting off the scales i hit Interstate 80 and Crank her on up To 75 on flats usually take summits at around 40 deppending on load i try to keep my EGTs under 1300..

I get 12.5 in my truck on 38s with stock gears. Thats hand calc and mostly city driving.

The Diablo adds lots of timing which is probably why your fuel mileage is up. But I bet its also streaching your headbolts.

My buddy has a CC/SB on 37's and stock 3.73's his lie-o-meter says 11mpg. I'm sure it's less. I dont even bother checking anymore. The Diablos run a LOT of timing... that's how they make their power. It's more of a "fooler" than a programmer.
