Thank you for contacting the Helpdesk at Skunk2 Racing.
The factory GSR intake manifold is a two stage manifold that utilizes internal butterfly assemblies to alter airflow in order to generate better low end torque as well as high end horsepower. Swapping to a single stage manifold such as the Pro Series intake manifold will result in slightly lower bottom end torque, but significant power and torque gains throughout the mid to high RPM's. Installed on a bone stock engine you would see a slight dip in the graph early, but would see about a 6-8whp gain after 4500 RPM. With ECU tuning you can eliminate the dip down low by re-optimizing the program for the single stage manifold.
To directly answer your question you do not need aftermarket camshafts to see legitimate power gains out of the Pro Series Intake Manifold for the GSR. If it were my build my next purchase would be a Hondata S100 so that I could tune the ECU to optimize for not only the Intake Manifold but the other mods as well. Not only will you see significantly better power gains, but improved drivability as well.
If you have any more questions regarding Skunk2 products or policy please let us know.
