The butterflies measure 1 3/4" which is pretty large, 1 11/16" is pretty common on a Holley carb around 750 = 800. There are no venturi's or boosters so I think the throttle body flows air pretty well when compared to an average carb. Inglese uses this system in a Weber carb look-alike system using 8 injectors. I would think you could use the current air valve and add 8 injectors to a carb type intake and get more even fuel distribution. You can also run dual throttle bodies on a tunnel ram or cross ram.

We've been using the EzEFI for a couple of weeks and the only issue has been a little rough running until warm. There are no cold start or cold running tuning options for this system, so the only option to fool with is the target idle air fuel ratio.

By rough running, I mean after a cold night you can reach in and start the car, it runs a little rough and can die once or twice, then keeps running and get's smoother once warmed up. When warm there are no issues at all.

Things I'm trying are different target air fuel for idle, and higher idle speed setting. I also did not connect the power wires to the battery as the instructions said to do in bold print, I moved them and it got better. They say to observe TPS volts at idle and if you see any variation, it indicates interference perhaps from the power supply connections if not connected directly to battery. I connected to the power junction right next to the battery on the radiator support, did not see any variation of TPS signal, but DID see a flicker on the rpm signal. I also moved the tach wires as far away from the spark plug wires as possible.

Here's a video I did of cold startup.
