Fuel Injection Questons

I am considering going to fuel injection. I really need a different carb, and in lieu of that price, I am considering FI as an option as well.


I am only considering tuneable, multi port injection.

So far I have looked at F.A.S.T.. I know Edelbrock offer MPI as well.

If you guys have any suggestions or first hand experience, it would be most appreciated.
Those Holley Terminators/Dominators are hard to beat since they have so much tuneability.
