Fast Ez-Efi??

I have been researching this too, spent a lot of time in the EFI board at chevytalk.com, lots of very experienced installers and tuners over there.

Aside from Megasquirt, the Holly systems seem highly regarded, both the HP and Avenger EFI, for their plug-and-play aspect as they actually work.

The HP system is a laptop tune system and in it's kit form comes complete less fuel pump. The Avenger system is hand-held controller based and comes complete with fuel pump. Both systems auto-tune initially and both include spark control. Plus the Avenger system is upgradeable to the HP system with an ECU swap. Both are rated at 900cfm, capable of supporting up to 600hp and have MPI options. Both are square flange bolt and go.

Pro Products has delayed their spark control Powerjection+ Plus system indefinitely, not sure I want to wait that long...

For $1999 at Jegs, I am leaning towards the Avenger EFI system for my first EFI project. Ultimately, I do want to play with Megasquirt, but I'd like to get my feet wet with a safety net.
