The intake will perform. You just have to be willing to put in the time testing and trying a few things to find what works for your combination. It works out of the box but it can be much better with some time.

As has been pointed out, I run it in NSS and can run under the A (10.00) index with it. Its on a plain jane 49x build with MW port SR heads and an Indy S2 flat tappet cam with 12.5 to 1 comp in a 3600lb car in NMCA NSS trim.
