Reply to "Atomic EFI vs. FAST EZ-EFI 2.0"

I have not used the tbi style Avenger units from Holley but we have done several of the HP and Dominator units. We have used Holley EFI stuff in the past and have never liked them all that much but with the new units they have really hit the ball out of the park. They tune easily and can be bought with all sorts of different wiring options. They are also quite versatile allowing them to be used with newer motors as well. We are also big fans of the Haltech and Vi-Pec ecu's however these require considerably more time input as they must be wired in for most engines. The throttle body units themselves can be bought from FAST separately, have most sensors built in and can be used with just about any aftermarket system.
