Another question, my BOV actually chatters when I rap the throttle a little from idle. You can see the piston in the BOV chatter or shutter real quickly. what is that. Also should my BOV only open after a quick let off of full throttle.
I have the turbo smart billet BOV that boondocker offers as the upgrade.
