So the Holley Projection 4DI system I have sitting in my garage is pretty much worthless???

Certainly not worthless. They still command >$400 on ebay. As 273 says, the last 4Di system added sensors for Pman and IAT, so should work much better on a daily driver. Indeed, I suspect that the last Pro-jection 4Di is essentially the same as the current Avenger, and the later just added a small user-interface box so you don't need a laptop to tune it.

I expect it would work fine as long as not over-sized for your engine. Of course, you can put in smaller injectors to match your engine, though those injectors cost more than MPI injectors and are a bit confusing (color codes). Best if you have the later Delphi injectors, which are "flat-top" with side connectors rather than the older injectors with round-top connectors.
