I install a New HKS SSQV3 Black and after 15-20min. I heard that the BOV sound start discharging different like it have compressor surge sound (flutter sound) sometime soft & sometime hard depending on the throttle response and then sometime start to discharge normal (the whistle sound) my question is, is that a normal thing for the HKS BOV? it suppost to work like that? the previous BOV (not HKS) didnt have this issue THANKS!
