Rich I have been waiting for the dual sniper system to be available to install on my 426 hemi. It has a Stage V manifold. Is the equalization port enough of an opening to balance the throttle plates?

I'm lucky enough to know and live within an hour of Matt Bell of redline motor sports to help set the tune.
