[GofaST4life]

This is my first DSM, and im already having a lot of fun learning new things and doing the work myself...im sure ill have more questions soon, but i wanted to now something, how imprtant is recirculation from your BOV to the intake? What are the pros and cons of recirculating and not recirculating?

Welcome, use the search feature, you'll learn alot more that way. Click on the search and try typing BOV venting, or BOV recirculate. Anyway, venting your BOV can be ok, if you do it the right way. When not done correctly, it can lead to unmetered air being fed to your turbo, causing hesitating, sputtering, and horrible gas mileage. Good luck .

That is the small part, the main part is losing METERED air.
