Sounds like you're having the exact same problems as me my bov isn't as loud either, i got mine hoping i wouldnt hit fuel cut but didnt expect it to give lag. I've set mine so it spools fine just don't rev it high in 3rd or 4th. You'll never be able to get it right with just the actuator because if you have exhaust and relocated filter you are always guna get boost creep. Suggestion would be some kind of management.
