This isn't the right section for a super duty, this is for OBS trucks.
But are you 6spd or auto? In my experience with diesel trucks, the 6spds like to be ran further out RPM wise, to 2,000rpms or so, to get best mileage. But the autos like to be babied and shift between 1400rpms and 1800rpms. I dont know WHY this is.. maybe because fueling and boost is different between straight drive/auto, but thats what I've come to find out.
