Just bought a 2010 cummins and love the truck but hatin my mpg. and at 3.60 a gal im really hatin it. If I remove my dpf and just run a full 5" exhaust and a H&S tuner would this help my mpg? How much could I gain? And since I did just spend 50 k on this truck Im worried about jackin it up? Any worries?

 

i done h&s 5" tbe, edge juice with attitude, k&n ram air intake...i get 17.5-23.5 with mine...bout to do the egr cooler delete

 

no worries as long as your state doesn't emission check

mpg... i get a little better after deletes, but before i was babying it, now i find my self flogging it because i can

i could probably get to the 19mpg mark if i babied it.
