Has anyone out there taken the dpf off and checked fuel mileage? Just curious cause you hear things but it would be nice to know if its true. I'm a little dissapointed in the mileage on my 07, I get 18-19 mpg highway but gramps can get 24-25 on his 04 5.9 side by side test so if a guy could get another 5 you would be in the ballpark.
