Tial vs. Synchronic BOV
That car is experiencing compressor surge. A tial should give off a full "woosh" sound if set up correctly, which that car is not. My guess is that the spring is too tight, causing it to rapidly open and close when venting. I've actually watched my roommates tial do this on his turbo gsr, since he has too tight of a spring on his.

That is how a properly set up tial should sound.
