FAST Ez-EFI is the shit. I know many people running it and it is just a badass all in one kit.
I definately recomend it over any other FI kit out there.
The red truck is a buddies with a big power 498 BBC and the fast works great. I have more friends I can get vids from if you really like.
My buddy has electric cutouts, and when he opens them you can hear the motor actually change how it runs to compensate for change in exhaust flow. Way cool.
