The only prob with the edge is there is no tranny control. I'm not sure if it's an issue on the 7.3, but the 6.0's are tearing up trannies with the edge. I really like the edge too, but it bugs me that the Attitude monitor has read outs for everything but tranny temp. If you've got a manual trans then it's no big deal, but with an auto you'll need to buy a tranny temp guage.
