mine used to move as soon as the cable was touched. if it did not close then you'd be losing air. | |

Pop your bonnet, pull the throttle cable and watch the DV then! | |

That is because there is not enough pressure to open the DV, so it comes back out where it has come from (like having no DV), hence the slight flutter. | |

Shinee was telling me that the chatter was the sound of air being forced back through the wastegate, and the wastegate opening/closing VERY fast. i think. | |

the chattering with BOV's is just when you lift off gentle.... the air farts out rather than surges out | |

my noise is due to me removing the recirc valve and fitting a blow off valve. i was under impression it is was just compressed air | |
