Stick or auto, better off with custom tunes instead of canned ones, although I have an edge EVO but on my last stroke it was heating the tranny up pretty good, current truck tranny stays fine. I have one kause it was free
i think they just arent where its at on the 7.3. the custom tunes are cheaper, add more power, and they protect the tranny better. i have a buddy with the edge and its nifty but it just doesnt match up to the custom tunes
