I guess it does depend in which terms thr original question is loaded ! LOL
Im not forgetting that, hence my comment that you missed about afrs

What we are both missing is that efficenciey varies at different rpms, and 40lbs of air at 5000rpm may give more bhp slightly than at 7000rpm with the same airflow even for the same AFR, due to increased parasytic losses and also of course the fact that you might be hitting PCP too late in the cycle at lower rpm if its a high comp engine.

But the moment you take things like that into account, you simply can NOT give a generic answer at all
