I've seen measurable gains on mild builds by doing multiport EFI on dual planes, have one on my car. I started out with an EFI'd single plane intake, went to a dual plane modified for EFI and the difference was night and day, from idle to wot. The added runner length and/or smaller plenum area proved beneficial, the exact opposite of the Pro Flo/Mini Ram type stuff.

Opinions and results vary. All depends on your setup, as you mentioned. I should've mentioned that.
