I talked with a rep from Edge at a truck show (I have the Evo CS) and she said they don't do custom tunes but the ones that come with are setup to run with CAI, catback etc. plus as they update tunes you can update the Evo through USB. Plus the custom screens on the CS and the CTS are pretty sweet.
I had the edge evo on my 03 and it was great, but I read the sct is the best. Sent from my iThingy using Tapatalk
I have my Edge custom tuned and love it You can get them (or the custom Gryphon) used from $200-$300 all over the place. Having 4 extra gauges is pretty sweet also. SCT and hypertech don't have that option.
