I have 7psi waste gates. I have the gates referenced to the compressor housing. I'm only seeing about 4psi of boost on my gauge and I hear the gates opening up. They cosistantly open at about 4psi and hold the boost there. Could there really be 3psi of boost being lost from the tubing and intercooler to the engine? just seems strange to me that the 7psi gates are opening at 4psi.
