You're saying personal driving style overrides the widely-accepted laws of physics? I'm done with this thread.
We are talking about perceived loss not the numbers, I made that perfectly clear. On top of that you quoted some one who said with supporting mods there was no loss and he has a dyno to back it up.
I just spend a couple minutes reading on the internet about this physics you speak of and this is what I came up with.
At worst that area is not maximized by the given intake velocity at that time and harmonics + scavenging effect (nothing to do with tune btw but you can do some calculations using the open end formula realizing that the 1st 2nd and 3rd harmonics correspond to N=1,3,5 ect) but it certainly possible to have more power everywhere (except maybe near idle) from M50 + complimentary mods. What is a more interesting discussion is if the S52 manifold will always produce more torque at a certain RPM, even with significant NA mods. I think eventually the M50 will be able to keep up and then outshine everywhere else. (Unless you had cams specifically tuned for low end (why?) and a helmholtz or something similar operating in the same range.)
Relatively speaking there will be a low/mid torque loss by changing plenum dynamics (in the way we are talking about) assuming constantly proportional volumetric efficiency. However,that whole quantity (torque) is also related to RPM, so adjusting the window --> beginning and start will affect your answer (consider the integral of a function of power vs RPM on the on the X axis from 0-3k vs 0-12k with everything else constant).
