    I just put a cobb cai on my car and it's making a noise that sounds similar to blowing on a jug but at a higher pitch. It happens at lower rpms. What could cause this? Boost hits just under 22 so I assume there are no leaks. It resonates and sounds horrible.

    Thanks for any ideas.

    The stock intake makes a noise like that too. It comes on around 2k to about 2300 rpm. With the Mountune intake, it's even louder. It reminds me of straw sucking noise. I hardly notice it now though.

    I never noticed this with the stock intake. The sucking through a straw sound I'm use to and I heard it with the stock intake. I guess I'll get use to this noise. Thanks for the reply.
