as in the bov is opening when boosting. boost is also going up and down when it happens, obviously.

if it has a dial on it tighten it.

Is it the model with two vacum ports??

If you have the vacum supply feeding to the port closest to the base of the BOV it will open uner boost.

The vacum supply needs to be feed into the top of the BOV so the boost pressure acts onto the piston and helps the spring hold it shut.

vaccum is on the top part of the bov
