Your right that the differences may be small, but at the same time, the edge CANT tune for an intake and exhaust.

The edge does have its place, for someone who wants the little gauges and display, the edge is pretty much the only choice for them. SCT is coming out with the comparable livewire soon, but its not even in the same price bracket at the edge.

They are both decent products, both will give you great gains over stock. I am just posting my experiences and feelings! No hard feelings to the other vendors who sell the edge!
