The rest of this sounds like a commercial for Megasquirt

To add another opinion from a former owner/user this Holley thing is a 
POS. One of its biggest problems was lack of dynamic range, if you got 
cruise set right, power was too rich, etc. And the fuel pump drive was 
duty cycle controlled to add another dimension to the problems. However 
Megasquirt could probably work with the throttle body.
