I explained it earlier in this thread.

i think i mentioned this earlier in my posts.. Well something along the lines of compressed air or wasted air going back to the turbo if the BOV is too tight which will cause this flutter via the wastegate/screamer pipe.


Simple: if u dont like the flutter bov sound then buy a plumpback bov.

But if u like shitloads of noise then buy a trumpet bov and add a screamer pipe for the extra noise.

Bear in mind that if the spring on the bov is too tight then u will experience a flutter sound rather than a loudass whooosh...

Nomsayin?
