My F350 has been tweaked, with a tuner and dpf delete, factory 400 hp 800 tq, now it's 600/1100 and it get 18-19 @ 70 empty, it's 4x4 or I'd get better.
So if the factory decided to then they would get 1,000 ft lbs easier even with emissions
I seen the dodge commercial he's referring to and it's a class mpg, meaning they get a best of 850 Torque, and 25 mpg, not both on the same truck. When u go look at the new dodge diesel they will have no mpg rating on the sticker.
If it does get 25 mpg hwy it's a 2wd @ 55 mph, which I will be very close to, but who does 55 =)
With my lance 850 I just went from Indiana to Grand Junction CO and round trip average speed was 63 and I got 13.1 mpg
