I don't dislike the Edge at all. It's a great platform for delivering custom tunes (so is SCT).

The Edge Evolution, CS, and CTS are all designed for STOCK trucks and must maintain CARB certification. They are not customized to your calibration/hex code, driving style, objective, octane, towing requirements, city/hwy mix, etc. Bottom line, the Edge canned tunes are still a compromise designed to make 'most' owners happy.

Custom tunes will blow away the canned ones.

 

Shotgun, this should be your sig...

 

I personally recommend the SCT. I had an Edge, and it was nice. The 93 Extreme was a great setting. really juiced up the truck. The towing was good cuz it kept the tranny in check. But after switching to the SCT, I am blown away by it. Not only does it have the canned tunes for 87,91, and 93, but you can add "towing" to any of those options. Edge has a towing tune just for towing. Also, w/ the SCT, I can take my unit to an authorized dealer and get a custom dyno tune, something that can not be done by the Edge. I have never owned a Gryphon, but have always heard great things about the PHP group. Again, these are just my opinions.
