I installed my AFE intake in May and noticed a smoother throttle, and felt like more power. MPG down because I drive it a little harder now. I am in the 3,000 mile per year club. My job doesn't allow me to drive it dailey. It would be hard to sell projects/improvements to people when I pull up in a BMW and they drive chevys and toyota's. So on the weekends I tend to have a heavy foot.
