Noob hypothesis coming up. Please be gentle.
I would have thought that with forced induction imperfections in the manifold design would be hidden. That is, air is forced in (and out) so it hides poor design. (I am not suggesting the FA20 is poorly designed.) I would have thought that the biggest gain, percentage wise, would have been for normally aspirated and even then, given the standard rev limit, it would not be a huge gain. Significant but not huge.
