I would pay the extra and get a Terminator, if sticking with Holley. EFI is NOT the part of a project to go tight with the budget - you get what you pay for.
Also integrate the ignition system with it. A Dual-Sync distributor will give the ECU better (quality) and more (quantity) of information on what the motor is doing, which will make the system more effective. Also, by controlling the ignition, the system will run MUCH more smoothly. I agree with JLM. There are a bunch of performance-guessers who "think" that throttle body efi systems "need" single plane intakes. Then there are people like JLM and myself who have actually tested, and found the truth. The dyno chart attached shows my dyno testing, comparing a P4B vs a Torker II and a Holley Street Dominator. The motor details are in my signature below. I'm using FAST XFI Sportsman (basically an EZ 2.0 throttle body, but with a more powerful/tunable ECU) system, with ignition control.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
