MADDOG is on a distinguished road

I have not seen any specifics on MPG gains. Most of what I have experienced is more due to the octane tune selected.

Programmers tend to richen the mixture and move the torque/HP curve down in the RPM band and sustain them longer. The result is that the truck feels a LOT better and the increases tend to affect your good judgement. In other words, your right foot gets heavier.

My experience with the Predator since I installed it was an increase of just a bit above 2.75 MPG highway, a little over 1.25 around town. I suspect it would be better around town but my foot is always in it...LMAO
