Hey all,
New to this forum and very new to the WRX thing, but hope that I can learn a bunch. Currently have a stock 02 WRX.

I put a cold air intake on it, and Im getting a big "PPSSSSHHH!!!" every time I get off the gas and shift, a lot more than I thought I should be hearing it....I can also hear the turbo spool up passing what seems to be more than normal? Funcion of more air coming in due to the intake? IM clueless.

So my question is....should I be hearing this at all and is it normal? The noise is coming from the turbo area itself, not the blowoff valve area. All connections look only has 6k on the motor.:confused:

I appreciate any information. Thank you.
