21 plus on the highway

 

Im at 20+ on the hwy with 285.

 

my boss has a 07 6.7 and he is only getting 14-15mpg empty and 10-12 loaded, and he cut off the dpf but he has 4:10 gears but people say that its bad because of the low rearend

 

after the turbo swap im at about 22 75-80 mph

 

13 on a good day seen 15 once or twice got 2000 miles on truck now with 6 inch lift and 35 1250 17 nittos trail graplers mt need to do deletes asap

 

12-13 empty, 9-10 pulling horse trailer or 28 ft fifthwheel camper

 

21-22 interstate doing speed limit. 23 on hwy in the Delta.

08 Dodge 2500 Crew Cab 4X4. Toyo MT 35's. Smarty. S&B Intake. EGR Delete. DPF Delete Soon!

 

I just avg 17.8 with about 400 miles highway, and 40 or so miles of city. Not as good as I hoped after the deletes. It looks like the guys with stock tire size are doing the best. But I also suspect those that are putting up the best numbers are also 2wd.

 

I have gotten up to 18.4(calculated) empty and 10-12 pulling up to 19k trailer depending on the speed. 4x4 and stock tires.
