Can someone explain how the valve works?
I can audibly hear the valve pop open and close switching between sport/comfort while in park, but as soon as I put it in drive, I can clearly hear the valve close. Does it only open when necessary, such as full throttle? The car is warmed up and idles below 1k.
Does locking the valve open by disconnecting the connection make it louder at lower RPMs? Any videos before/after?
