WOW what a difference 400 bucks and 15 minutes makes. Just got my Edge Evolution programer. I can't believe how much more power it unlocks, and the added fuel milage is incredible. can't wait to switch out my exhaust and put an AFE stage II on. I put the evo up on 100 hp for poops and giggles! and had a check engine light come on though, some thing about too much or not enough presssure. but it didn't say what kind of pressure, so i backed it down to the race setting. thanks for the suggestion of the Evo.
