Stock bov? Ditch it. They suck period. I dont get how some people keep them on their cars. I replaced mine with a Forge RS and it made all the difference.

You think the 9 bov isn't strong enough to hold the pressure??

A boost leak test will tell you if it is leaking. Mine crushed slightly holds 30 psi everytime I test it

It is either the BOV or you have a boost leak...

Although it might not be much, but check your throttle body shaft seals. Tested and mine leaked like a ****. Ordering the seals today...
