Best fuel injection ?

Avoiding the TBI vs Port EFI argument you'll probably find the Holley Sniper is most commonly used. That's not to say FiTech, MSD Atomic, and Fast EFI are bad either. Edelbrock has their Port EFI system, a few folks have reported some fitment issues in the distributor area but other wise are pretty good to.

I have a friend who has installed about 9 Sniper EFI set ups for friends and he loves it. Now that Holley has an in tank EFI pump and regulator that is made the for the stock tank, that takes the extra work and some cost out of the fuel system.

How are your computer skills as they, like a carburetor will need some from of fine tuning?
