In order to make gobs and gobs of power, you want to inhale and exhale as much as air as possible. This in turn means you can burn more fuel. This is where forced induction comes into play as turbocharger and supercharger kits will increase the mass flow rate of air into an engine. However, when picking a forced induction kit, you need to ask yourself one question; "at what PSI can I meet the required mass flow rate of air to reach my goal for XYZ rwhp?" More often than not, stock rotating assemblies will be the limiting factor in reaching your horsepower goals. The additional PSI will raise your peak cylinder pressures which not only means added compressive force on your pistons, but increased cylinder temperatures which leads to detonation.
I'm not guessing, I was told this by my tuner who knows what he is doing and understands how the engine/boost works better than any of us. More air means more fuel means more energy. You said it yourself, you are looking for a target CFM...

Yes btw, that torque number looks off. I would expect something lower from the mustangdyne. More like 290.
