So lately I've been noticing a quick hissing noise during throttle blip - first started noticing it when blipping for downshifts, but can induce it blipping the throttle from idle. I've seen the other threads that talk about a knock or pop during blip, and I definitely do not have that. It happens at a rapid blip of the throttle and just sounds like a very quick hiss, almost like you can hear the air induction. Noise won't happen in other kinds of driving, rolling on throttle, WOT, etc. No other odd noise otherwise.

Anybody else notice this?
