Hi guys,
I installed this air intake on my 2001 audi tt roadster and I love it for the most part. When I push down on the gas pedal about a third of the way down I hear this high pitch tone coming from my intake. Its not the turbo spool and its not the air leaving the intake. It sounds like something is loose and air is escaping somewhere that its not suppose to escape from. I took it all apart and put it back on thinking that I missed a screw or something but it still does it. This only happens when I have the gas pedal down about a third of the way, when its past that point you can hear the intake working properly.

Any suggestions?
