Not done too much too her since I am in the process of remodeling so my truck hasn't gotten much love besides finally wiring my tow mirrors up. I do have to say props to Lew and his tunes because now he has gotten my truck the power and MPG I love. Not bad at all for a truck with 7" of lift and 35s. Before anyone bashes that its fudged or whatnot this is so far with 5500 miles on this tune and I live in the mountains of TN here so theres no flat land coasting or much of being able to cost down hills as our mountains are literally up and down steep grades.
