Seems like some people get what I would consider great mileage on these stock 6.7L's, but I got HORRIBLE mileage in stock form (as I know others do as well). 12 around town and 14.5 on the freeway. I drove it like a grandma trying to suck down as little fuel as possible. I just did a DPF delete, intake and H&S programmer and have picked up 4mpg average, while driving it harder then I usually do. I'm sure after I start driving it easy like I use to, It will get even better.
I should have done these mods a while ago..
