I think it could be for everyone, but if someone wants to be a "Tom, Dick or Harry" then by all means, please buy the edge.
It is my own opinion that custom tunes have a place on ANYONEs vehicle who wants the best tune they can get. Even if you dont get our BamaChips tuner, any WELL TUNED Xcalibrator 2 should perform better. And not just the SCT base file for that vehicle.
