    What is the REAL expected mileage on the newer dmax? My 2009 on average gets 12-14 mpg city / 9-11 mpg towing enclosed 28' sled trailer
    Scaled weight with truck and trailer loaded 16,500# ( 4 newer sleds/gear/full fuel station) Truck is completely stock w/ 30,000 miles

    With the PDf that is about as good as it gets. I have a banks air intake, bladerunner manifold and down pipe, XX duel fuel filters, Fass fuel pump. More power but the milage has stayed the same.

    Dmax mileage

    Thanks for the response. I considered doing the complete Banks system which is by far the best out there, howver, am still concerned about the mileage benefits. Would hate to have that investment and remain the same for mileage! I'm sure the power would be incredible, but I am not disappointed with the factory set-up. I AM after better mileage!:cool:
