That sounds like a failed blow off valve.

Sounds like the turbos spooling to me. Mine sounds similar. Did it just start sounding like this?

Yes, just started doing it.

Getting it checked out first of the week.

I still hear the blow off valve "pffftt" if I let off quick like I've always heard.

Had a wastegate sticking, but it's working now. Doesn't always make the sound and I've towed trailer with it with no sound or power issues? Perhaps I am just oversensitive?
