JFairman I believe just vents it to atmosphere so it just works as a mini BOV.
The best.

Could be that it won't open at lower idle vacuum...that's why I'm asking. And I may just keep it anyway for the small benefit of acting as a mini BOV.
As to Jim, I think he was just getting a woody with the blowoff noise it makes. There's a little bit of ricer in each of us. I may do the same thing, and hook a whistle to it.
