Question Engine Noise - Please Help

Sometimes when I let off the gas to push in the clutch and shift, I hear a strange rattling noise coming out of the bottom front right of my '02 WRX. I have an HKS SSQV BOV and an AEM Cold Air Intake. If the turbo spools up a whole lot, after heavy accelaration, I do not hear the noise (rather the BOV emits a loud air blast) - it only happens if I push the clutch in about 30% and then release to shift. It seems as if the BOV is blocking the air and pushing it back out the intake. Is this possible? If not, what could be the problem?

Thanks in advance....from a scooby-newbie.
