need to ask a quick question

[briggers]

when switching off engine i have a turbo timer and when that eventually cuts the power the engine lets out a small phhwwwwww. lol some may think that was just a fart but no it sounds like as if there is a small animal blowing a small trumpet under my car. i think it has something to do with the turbo but im no mechanic. does anyone know? is it bad if they do i dont want the turbo to be on its way out or something.

Can you get a sound clip of it ?

I doubt its anything bad, probably just venting a small amount of pressure.

It wouldnt be anything to do with the turbo because it wouldnt be under boost on idle when the timers ticking down.
