newbie question

[mys15]

have a 99 silvia s15.

recently i put in a intercooler,bov and k&n filter, and now i cannot hear the turbo spooling. is it normal?
when my car was stock with just a cat back exhaust when i floor it i can hear the turbo now with thoose mods i can just hear the exhaust and it seems like i'm not getting any power.

thanks

You should hear more induction with a filter on. The FMIC and exh should give you a slight increase in boost and also slightly faster spool up.

Your car is weird

Boost leak some where. the bov maybe in the open positon, or boost is escaping from one of the joints.
