I don't know which one is the best I think they all have there good and bad points but I have used both SCMT and the EDGE Evolution and like the Edge a little more. Just my opinion for what it is worth.
I have a 2003 F-250 Super duty 7.3 Deisel Auto 4X4.
I would like to know which preformance tuner is the best on the market?

I have used bothe the Super chips dual and three programmers, as well as the Edge Evolution. My vote goes for the Evolution.
PS: I did however have a problem withe Edge on an 02-Manual truck over the holidays. The programmer messed up the PCM, and now the truck will not run. The dealer is having to put a new PCM on my buddies truck. Edge are closed over the Holidays, so I was not able to get a hold of anyone there to see if they can help.
