Shouldn't make any difference as long as your pressure is rising 1:1. If you can't adjust your air bleeds easily, add more enrichment on the PV circuit.

Do you have extended vent tubes pointing into the charge stream like so?

extensions as pictured alone richened up my carb'd setup quite a bit. It's quick and easy. Might give it a try.
