that would be the HFC's. or what some people refer to as deceleration hiss. apparently its always there, just more audible with an HFC.
quick question, my ERZ/CNT HFC makes a super annoying rattle when accelerating at full WOT. does this happen to you too? it probably happens somewhere around 4k rpm. its pretty damn annoying and im going to have to get rid of these things if it continues.
