Good questions, trukki81! Yes, I'm the same "JackandJanet".
As far as I know, ALL programmers are quite easy to use. I keep telling people a 5-year old could install one on a truck and I honestly believe it. Most of those 5-year olds could also push the buttons that would program the PCM. It really is VERY simple. Most problems occur when people don't quite follow the directions (although there have been some other problems that I talked about earlier).
Updating a Gryphon is quite painless. The Pegasus application is very simple to use.
I think you're much better off getting a Gryphon instead of an Edge. You're going to get fantastic customer support from Bill and Corey and you'll get better tunes - for pretty much the same price!
I've heard very good things about XCals from Justin Starkey at VMP and Mike Troyer at Troyer Performance too, so I doubt you'd go wrong with either of them. Anyone else? I dunno.
Are they created equal? Sort of - as far as being able to program the PCM. But, the Gryphon lets you monitor operating values in your truck as you drive it. That is worth a ton to me!
I know nothing about Diablo or SCT.
As far as I know, Bill specializes iin Ford applications, but this is much more than just Gryphons. Just read through this forum, especially the diesel part, and you'll get a hint of how versatile he is.
In this forum, we don't mind questions, so feel free to ask.
