Call KEM Performance or Spartan Diesel. Either one of them can fix you up.

10-11mpg sounds nice im only getting 8mpg if im lucky. i want the spartan diesel kit like ASAP, but i really gotta wait till like summertime, hopefully by then some other things will be out too.

like the above posts said, call spartan diesel and they'll hook you up.

gears won't help... with lift and bigger tires the 3.55's will be a real dog. To truly address the mpg's you will have to remove the DPF, cat and address both the engine programming and the tranny....... and IMHO you still won't be happy with the fuel economy... I'm not sure why these things are as thirsty as they are. If you are towing anything significant, fuel economy goes down to 6-9mpg... big rigs, for the love of God, do that well.

I borrowed a buddys F450 dually , towing my 8,000lb toy hauler on a mostly flat trip (phx to Yuma) I averaged 7.1 mpg. My 7.3 on the same trip with the same camper got right around 10 mpg,
The power was decent in the 450 I could not feel the camper behind it. Nice truck but the milage is a problem
