Hauling a light single trailer around with number 2 diesel I'm getting 5-5.5 mpg. Number 1 diesel it drops a full 1 mpg. We mostly haul heavy sets and I'll average 2.8-3.5 mpg. My truck came with a Pittsburg Power box on it. I've always ran with it off or on stage 1. I've never liked it because it's not true power efficient power. I want proper programming and everything in that motor to work at its highest potential. Can I bump up the hp and torque just with the programming? I'm looking to get up to 600-620 hp 2050 torque.

What is the gearing in that truck of yours? Which transmission? The proper gearing will play more into your day to day operation than a big horsepower tune. Also help with fuel.
