*UPDATE:
(Also see the new RX Manifold with optional sub-injector bosses. p/n 13522331)*
As the graphs show, the RX Intake Manifold adds a lot of mid-to high end power, with at a slight compromise at the low-end. But with the addition of the larger RX Throttle Bodies, the low end power is restored and even more mid and high end power.
