Searched for the anwer to this and found plenty of posts where people were asking but no anwers.

Anyone know the difference between the new XFI setups and the older setups? I have an LT1 road race build in progress right now. Ditching all unneccescary wiring and plan to have only the Aftermarket computer, a fuel pump switch, starter switch and brake lights.

If you don't need blower, nitrous controls, etc. Is there any advantage to the new XFI over the older set-up?

Any other non-Fast computer set-ups worth considering? (other than Motec, don't have $6k burning a hole in my pocket).

Thx
