Loud blowoff valve

You will not loose boost pressure but you will loose response in the turbo spool with a atmospheric one...

You won't. No noticeable difference whatsoever.

Hmm, i just thought that the air that the atmospheric bov lets out makes the turbo to start over and spinn from a almost stand still, and when using a stock one it pushes the extra air back and before the turbin to have it spool up faster... maybe you just notice that if you compare to have non bov and the stock one...

In theory there should be a difference, in practice there is none.

Okay, but as you said before it´s not a good solution if you using MAF correct? as it will give bad reading and it will go fat for a split second...
