When I bought my car it had a Steeda delete on it. I bought the CFM because I wanted to route my TurboSmart BOV to it to cut down on the negative psi venting. Been running like that for a couple months now and it is much more enjoyable now that I only vent when boost reaches 10 psi or so.

What does a pressure port have to do/why would that be needed in relation to an OCC?
The DM Stage 1 OCC kit connects into the intake manifold/PCV valve hose connection. Most oily blow-by contaminates travel this path from boost into vacuum transitions, where crankcase pressure has the potential to be greater, then the system immediately turns to a slight vacuum. This causes a fine oily mist that would otherwise flow into the intake manifold. With the DM Stage 1 OCC kit in place, the hoses route the blow-by to the OCC, where they can be filtered and cleaner air is sent back into the manifold. In turn the primary benefits are: cleaner air mixture, and less oily build-up on the valves and in the intake manifold.
Mounting location 1:
-DM OCC is mounted off the intake manifold sound symposer support hole
-Very easy to drain, as the drain valve can be accessed from atop the engine
-Quick install, mostly from above the engine
-The factory top engine cover does not interfere with the OCC
-Minimal hose lengths, minimal hose routing
-Sound symposer delete is needed, however we offer one here
-Only works with the factory intake manifold
I have the Mishimoto catch can which attaches on the frame rail beneath the intake (Mounting location 2 on Damond website.)
