Well you do loose a little in the lower RPM range with the FRPP but it's not really noticeable. The big advantage, for me, with the FRPP is much better A/F distribution then the stock manifold. I got mine for this reason. I'm not really worried about getting a few extra HP from the setup but I am interested in not having a cylinder go lean due to poor A/F distribution. The stock manifold does a good job with lower powered N/A setups but when you start pushing 10# and more of boost through it you can potentially get a lean situation in one or more cylinders very quickly.

If JPC ever gets it's cast version of their manifold back in production I will probably replace the FRPP with it for the same reason. The billet version is jut too much money for me.
