3rd newbie question...squeaking noise under boost

Hello

Changed air filter to KN Panel...I notice a squeaking noise under boost (sounds like a squeaking clutch pedal but its not)...it usually makes noise under boost when I shift gears or let off gas...Is this normal...I had not noticed over the previous couple of weeks. Only thing I did was change air filter on stock airbox and its resealed...thanks

Just to add info: I get the noise when I I lift gas pedal to shift (under boost prior to shifting) or just rev it to say 4K in 2nd gear then let off the gas I get the same noise.

If it sounds like someone kicking a puppy, that's just the BPV.

you're letting in more air with that filter. That's going to cause the bpv to react a little more aggressively.
