Default Is direct port necessary for cruising injection?

Iím looking at an MB OM648, BMW M57, or VW CBEA equipped vehicle, and interested in putting an HFS-4 to use. The intake manifolds are below. Iím wondering if a positive pressure (I think 5 psi on the OM648) at highway speeds will be enough to distribute somewhat evenly?
