I think the debate was mostly centered around whether it should provide a suction point for the valve cover vent. David says, "no" and a lot of members say dumping that metered air plays havoc with the transition from driving to idle. I knew the risks, and bought the item used. I've had no negative issues, however, it may be exacerbating my ongoing DV flutter issue.

See my above reply to Aaron. Yes, I can increase the boost with the MBC. I've not tried to see how high it will boost, however. My boost gauge 'only' goes up to 30psi. I have turned it up to 31 a few times, until I chicken out.

Like cams and turbo, intake manifold is really more money that I want to throw at the car, at least for right now. Maybe after the EVO owner's bailout package is passed by congress, I'll feel differently!
