Also, once you get your tuner remember that the best mileage that you can get is dictated by your right foot. So once you get the tuner and get the extra ooomph out of the truck and you go around using that, there goes the MPG's savings. Fun vs Cost, fun always seems to win.

Edge tuners are meant for stock trucks. You need a Gryphon and custom tunes to take advantage of intake and exhaust mods.

Level 2 is richer than level 1 and will not give you the best MPG. In fact, level 2 is the best setting if you have a 04-05 5.4L with an A/M intake (know lean issues, especially with intake mods).
