Can somebody explain why? Is it accurate? I don't remember reading about this anywhere and it's not like this on the AccuSim FSX Spitfire either.!

In short: You put load on engine, RPM decreases, so air usage of engine drops, but it does that more than output of supercharger. I don't have Accusim, but I think I saw the same in their videos.
