I've used both the original FAST and a couple XFI's now and the AEM is still ahead of the XFI when it comes to features and capability. I'm in the middle of an XFI setup right now on an all aluminum 427 ford with an F1R Procharger, I went with the XFI because that is what the car owner wanted. Will it do everything I want it to do and be very tame and driveable? You bet, but I wish I had some of the other features of the AEM, especially the timing retard vs. IAT-- especially out here where it can get to 110F in the summer.
Don't get me wrong, the XFI is a very good box but it's a bit on the "simpler" side compared to some of the other offerings out there. At the same price point of the XFI there is also AEM & Autronic, both of which are great boxes with more features, however neither are as "newbie friendly" as the FAST. I have not messed with a MOTEC yet but I really want to, same goes for a Delphi UH4.
If you want, you can download the AEM ProTuner software and install it for free and look through all the tuning options-- it's way more "in depth" and setup much more for guys with EFI experience when compared to FAST's C-Com WP, the Accell Gen VII, or the Big Stuff 3, all of which have very well polished and very "beginner friendly" interfaces.
