David, search dsmtuners for calan and his catch can and I promise you will be happy with the results. Hell I'm buying another one soon.

the other problem you have with doing large crankcase ports routed to a catch can, then routed to the intake, is you will significantly alter the metered are by the MAF. If you are running the stock size port from the valve cover, you can get away with it.
