fuel mpg ???
hi guys&girls new member just started puttin on bullet proff egr cooler &oil cooler bigger chore than expected gettin about 16 mpg hiway lookin to get more 2004 6.0 82.000 miles any ideas bonestock motor not towin anything any help thanks blackcat00
and 16mpg is what i get with an intake, exaust, and programmer.....so dont expect to be in the 20s
the SCT would proly help, and the straight pipe wouldnt help with mpg's but its better for the truck..... when i got 16 i was runnin 75-85mph with LOTS of hills but that was the only time ive calculated all highway mpg's
