Problem with Holley 4 bbl

Nevermind. I forgot. You already said 5". The PV makes ZERO difference at idle. There is nowhere for the fuel to go if it's blown or open. The boosters have to have a signal to pull fuel into the venturis and without the throttle open, that ain't happenin. Effectively, you could throw the PV in the ditch and tune correctly for idle.....so don't get caught up worrying about the PV "right now". That said, you are at a good starting point for the PV now though.
