Strange dump noise

[Cashpoint]

For some reason my car dumps the wrong way around... Let me explain in previous turbo cars I have had at low boost levels i sometimes got the wastegate chatter noise ( i know it\'s not the wastegate but we all know what the sound is) while at higher boost the BOV opens and i get a whoosh noise. On my FD it\'s the wrong way around, higher boost has a chatter noise and low boost i get a whoosh noise.

Can this be due to incorrect piping, i\'ve looked on other threads and the BOV appears to be in the right place.

think this is due to the fact your bov is attached to the recirculator pipe off the 1st turbo so at low boost it blows off through there but at high boost it uses the 2nd turbo which recirculates , my 2p worth anyways :0)
