We went Holley Sniper w/ Master Kit from Summit, and after some initial issues that were due to the ignition system, we're very happy with it - the truck's never run this well, and mileage went from 11=12 to 14-ish.

I found the holley forums to be quite helpful.

I'll also comment that apparently ANY EFI system not only needs a sound engine, the ignition system and electrical wiring MUST be 100%. EFI will highlight any weaknesses - for example, a slight ignition miss that you'd be hard-pressed to hear/feel will show up as a false lean AFR, then the EFI will richen things up, leading to a spiral that'll drive you to drinking. Make SURE your electrical system is 100%, including the alternator, ignition setup, wire routing, etc etc etc.
