Higher vacuum is lower pressure. That is seen as less air, meaning less fuel will be injected. Which is the opposite of what you are talking about.

It is also very unlikely indeed that an air intake would cause more restriction than a mostly-closed throttle plate. At cruise RPMs, it probably isn't enough restriction to even measure.
