I drive a 2004 Chevy 2500HD with the LB7 Duramax. My city MPG went from 14.2 to 17.6.I was getting 19.7 MPG on the highway and now I average 23.9. I drive 600 miles highway every weekend and 200 miles throughout the week city. I was reluctant to make such a purchase, but it was worth it in all aspects. The performance tunes add some awsome HP. I played with them on the first tank and then started watching the savings. I haven't towed with it yet, but it's coming. I will update when I make the first tow."
