I have an '05 F150 5.4 V8 4x4 with 15,000 mi. Just installed an
Edge about 3 days ago. Programmed to level 2, it ran great in the beginning. Was averaging 17.8
mpg with more power. Reset to stock for comparison then back to level 2 and it never matched the original performance. Today it started vibrating (tranny?) in lvl 2. I swithed back to stock and now it won't start. The starter just spins without engaging. Edge says the unit didn't reset to stock correctly and are sending a new unit out. Anyone else have this problem or know what may be the cause? Seems like the
programmer shouldn't affect the starter but I'm not a mechanic. Thanks.
