no experience with the XFI but Kevin at fast has been more than helpful with my old "grey box" classic fast that I bought from Cooter and Jimmy. As for performance, the FAST was .13 quicker with a baseline tune, first pass, than the previous Accel Gen 7 was with 2 years of messing with it. Not saying that some of it wasn't me, but the fast is much more user friendly, and the accel support was non existent.
