Think best value is getting one from AmericanMuscle.com, I think SCT has an enforced MAP on their products (Minimum Advertised Price) since all online store have the tuners priced the same. They compete more over included services, think AM was first to offer lifetime tunes from BAMA when purchasing a tuner through them. Great perk I think especially for those who just want to cruise around and have the tune adjusted when a new mod installed calls for it. Won't beat dyno tuning but makes it easier than shelling out 150ish each time you put something new on.
