By adding a intake and DPF back exhaust, the maximum MPG improvement that you "could" achieve will be statistically unresolvable.
i.e. if your mods produce a .10 MPG improvement (which is generous IMO) you will have that much fluctuation in your MPG from other variables (such as seasonal climate changes, quality of fuel, driving characteristics, etc)
I would like to see one of our 6.7s put on a engine dyno, holding all the other factors constant, to see what efficiency an intake and DPF back exhaust would actually produce.
Even then, I think the error in the testing equipment would be greater than any realizable gain.
Sorry, i'm a little cynical towards the aftermarket vendors claims of "increased MPG" based on biased and statistically indeterminate data.
