Wait a second. I'm fighting conflicting info I think.

Freon's block diagrams for the 3-port solenoid show:
-- Energized = Wastegate references turbo inlet tube pressure
-- Rest = Wastegate references turbo outlet pressure

Based on that information, I would expect the solenoid to be energized (clicking) at idle just as I am experiencing. That is, when the ECU starts to control boost, it is allowing some 'rest' state to happen. My boost is working perfectly fine with the solenoid clicking at idle.

But TheMadScientist says this is wrong and it should be completely off at idle.

What am I missing or misreading here?

Can people who have this mod please just sound off on whether theirs is clicking at idle (regardless of it being as loud as mine)?
