Those 2 things are not compatible!.

I surely hope like hell you got that thing because you have some special application for it,.. because if you're hauling dryvan/reefer, etc. kind of competitive freight,.. you have shot yourself in the foot for having it.

If you're loosing your arsse because of piss poor fuel mileage, then for the life of me I can't understand WHY someone would buy such a fuel sucking pig of a truck?

What is the gearing?

What mods, driving styles, and things have you done to reduce fuel consumption / operating costs?

Hey rawze, yeah iv had the overhead ran and set a couple months ago and fuel pump rebuilt at same time. I have not done a injector leak down test But will look into doing so. The truck has 380,000 miles and has 3:36 rears I know a horrible ratio I drive in 17th gear at 60 to 65 and keep my boost under 20 at all times. I pull a tank on a dedicated semi local route. Just looking for some more mpg out of it.
