I have a 2006 LBZ (3500 ext. cab) with just over 186000. running empty, at posted speed, she gets 22 to 23. Pulling rvs, no matter what the size, she gets 11 to 12. With the Hypertech, it increases 1.5 mph loaded and 2 mph empty.

Increasing MPG
Running unloaded on the highway - meaning not towing anything - I got a high of 19.7 mpg in my '07 LBZ CC SWB 4WD, running 70-75 mph. I think that's the highest mpg I've ever gotten from a 4WD pickup, gas or diesel ('01 LB7).
