SOUND

I bought my pulsar 1.2 4 months ago. In the last couple of days, the weather is nice and i drive with my window open. I noticed a sound every time i
leave gas (even in small speed and gear)

The sound is like a whistle, like a turbin turning off, like air, only for a few seconds.

Nothing is heard when i try the same without a gear. Is it normal in turbo cars???

The sound is something like what is heard in this video in 2:07, when the driver stops accelerating

The noise is caused by the blow-off valve. See below.
