^^^^^^^^^^^ Exactly what Chad said.
I installed (upgraded the firmware) last week on my buddies XFI system to the 2.0 "self tuning"..... it is NOT self tuning.... but will correct a "close" VE table. And here's t he sweet part of the deal. I used a "canned" tune from their library and she fired right up. A very little adjustment - and we went for a drive. The car never ran better. I still have a couple bugs to work out in one spot (1200 rpm light throttle) but that's it. So it's pretty nice set up.
TO OP: Call FAST and discuss your application.... and see what tune up they have that will get you started. My guess is they have one. But you definitely need a boost referenced capable ECU.
