Could tell a HP difference right away. Added 1-2 MPG.

I knew I needed to try something to increase my gas mileage. I am getting about 10.7 mpg in my 2010 F150 King Ranch. The 6" lift on 35's definitely does not help. I was skeptical at first but I am happy I made the purchase. I am getting around 12.3 mpg now. I calculated it out and I should have paid this thing off within the first year just from the gas savings. I was a little surprised with the "drone" sound at first but it has been growing on me ever since.
