After reading on here that its best to have the OE DV and the AM DV connected i thought i would connect up the OE one. I bought the car with the setup where there is a AM DV and a vacume line with a screw in the end of it connected to the OE DV.
I took that vacume pipe off the OE DV and added a T Piece to the FPR and connected a new pipe to the OE DV.
Now i have both connected i seem to hear a whistling sound from the Turbo when accelerating slightly at 70. Is the OE DV staying open at certain revs and leaking boost?what can i do to correct this?
Also the AM DV is connected to the rear BCS.
Hope all this makes sense, any help would be appreciated.
