Message The small (vacuum?) hose that comes from the balance tube to the fuel dampener keeps getting blown off the connector on the balance tube side as if it was under high pressure. This happens almost every time I take the car out and hit boost.

Is this connection only supposed to be under vacuum, or is there positive pressure at times? When it does come off, the engine RPM pulsates (as I believe it should since the dampener is not functioning at this point). Idle settles down once reconnected.

Second Question... I am familiar with the notorious HONK from the air intake when you let off the throttle, but I am getting a continuos HONK as I boost. When I continue to accelerate and the car begins to hit higher boost levels the honk keeps on going... OK no canadian geese jokes here now, LOL! I am worried this may cause some serious problems, and could this be related to my first question?
