Greddy type S Bov valve... properly installed? pics inside!

Can't tell where it connects to from the pics. If it's connected to the y-pipe as I assume it is, you're fine. Looks like the vacuum line is hooked up right.

The "soft" and "hard" screw is for adjusting the preload on the spring. As long as the valve is closed at idle and opens when you let off the throttle under boost, it's fine. Some people have it open slightly at idle, too, but let's keep it simple.

The capped pipe on the intake is for the factory "BOV". Since yours is vented to atmosphere, you don't need to worry about it.
