I use the SCT SF3 for my 2006 and my 2010 Mustang GT's. I have never used any other tuner so I can only say that my SCT is a great little machine.

We have the Diablo for our 2001 Bullitt and the SCT for the Blue 2004 Mach 1. The White 2004 Mach is stock, so no tuner. Actually we have not had to use them very much, set set the initial tune and left it alone, except for adjusting the Bullitt for the 18 inch wheels. Both are good.
