That's effectively what the Rotrex kit does, just spins the blower at full potential using a wastegate to limit the additional boost resulting in moving the entire boost curve left. The exact same thing can obviously be accomplished with a vortech kit as well. The SI would get you part of the way there but a TI trim blower would be more comparable to the Rotrex in terms of CFM.
