I just redid all the vacuum lines on the car and installed a vacuum manifold and a 1g bov in the lower intercooler hose.
The bov makes the right noise when you let off. When it starts to make boost the car makes some very odd growling/whistling noise in the intake. Never did this before the bov. When driven with the bov hooked up it over boosts and you get the wonderful code 45.
If I just disconnect the bov then the car makes 7 psi and that's it.
The wastegate vacuum line is hooked up t1 style so turbo nipple to a orifice (red) then to a tee, wastegate actuator then to the solenoid. I say this because the wastegate vacuum line has nothing to do with the bov or the vacuum manifold.
I dont understand why the strange intake noises with the bov in the circuit and how the bov could be affecting boost if it has nothing to do with the vacuum manifold.
