TXS Boost control solenoid clicking at idle.......

I noticed some sort of clicking coming from under my hood last night when I was pulling into the garage. I popped the hood and whipped out my high-tech listening device (length of vacuum hose shoved into my ear.
)
What I deiscovered was the TXS BCS was cycling. it was clicking away and you could hear the air coming out of the vent port.
This doesn't seem right at all! THE BCS shouldn't be doing anything at idle, I wouldn't think. Why would the UTEC be pulsing the ground trigger at idle or other non-boost conditions?
anyone who has one, will you check yours?
thanks,
Andrew

the side port on the wastegate is the port that opens the wastegate under boost. the boost lines going to the side ports come before the BCS. if the BCS were to fail in the open position, your have boost sent to the top and side ports, eseentially cancelling eachother out...and the wastegate would be held closed due to the internal wastegate spring.
Can you say OVERBOOST!?!?!?!

I guess I'm a little confused, normally with no BCS the Turbo will send a reference of what it is putting out to the WG. A BSC modifies that signal to keep the WG closed longer so that you can permit more exhaust to go to the Turbo and achieve more power right? So I would think that if the BCS were fully open it would be like it was not even there and the WG would perform based on the spring inside it.
Or do you have 2 lines hooked up to the WG with a BCS?
