I disagree. The PCV should be used for what it is. I don't think adding it to for a tuning aid is the right thing to do. It should be included to perform its specific purpose and be a part of the entire system and just tune accordingly with it in place. Same thing you're saying essentially, but yall are makin it sound like it's used as a band aid, when that's not the case. Millions of cars ran just fine without PCV valves before they were mandated.
