You could be right too But if so, it suggests the spring tension is too high - great through the gear performance, not so good for the turbo.

Its the filter and supposed to make that noise. You'll get used to it! Not sure what it is, but sounds like the filter breathing!
I aksed the same question when I fitted mine as I thought it sounded odd. Incidentally, I took mine off and it drove better, DV too.
