It could be nothing, when my car had all new parts installed such as filter, dv and n75 the whirling to whistle noise of the induction/turbo had become more aparent. Im no mechanic though so someone should point out any faults

yeh this is normal, mines does this when giv it a little poke, this is the turbo spooling and dump valve dumping excess gas into air box. perfectly fine
