MY current BOV is a GFB one, and is a bit shit as it stays open and the spring tension is stuffed, causing the BOV to stay open on idle and accelration sometimes, hence I want to replace it.
Now i am not to concerned about retaining the sound of atmo venting.
IS a plumback substantially better over a atmo venting, from purely a performance perspective?
Furthermore is there any noise emitted from a Plumback? is it at all similar to an atmo venting sound, just lesser volume?
Finally what would be the best Plumback BOV to get, i understand this is fairly objective, but opinions are welcome...
cheers
