Anyone have any advice on where to start with this module to increase mileage on an07 6.7? Thanks in advance, Scott

 

i use mine for daily driving at about 40%, seems to up milage a little for me.

 

With my experience in my last truck, I'd keep it below 50%. Rail pressures get scary quick with the dial in the higher settings. Makes for good power and smoke though (although you'll probably not see the smoke on your truck).

 

i keep mine around 30 or 40% and it gives 1 or 2 mpg to my truck but i also have the edge

 

I was going to start it on 50%, but I will cut it back, Scott (I am going for mileage)
