My 2004 Expedition 5.4 (2v) loves gas, I love power. My Flashpaq done just as I expected, I recommend that after you toy around with various tunes that you revert to Stock with option 16 on 1-2,2-3,3-4 valve body pressures and highest RPM shifts 1-2,2-3,3-4. From what I discovered, the performance tune will in fact decrease gas mileage while the economy tunes 87 will in fact increase gas mileage. I love the firm shift and higher RPM shifts that my tranny now experiences. LOVE IT.
