If you search by hands the small hose that goes from turbo exit to the "T" piece before wastegate and solenoid you'll see inside the small brass restrictor.
You can use though a flow control valve from Festo, much better boost control and adjustability. I am going to order some valves from them (my choice is the valve with part code 151216) for me and some friends with standard or modified WRXs but unfortunately I can't find the part code for the hosetails(3,5mm inside diameter) that bolt to the valve, John Banks are you there?
Anyone else that bought in the past the above valve can help me?
