Thanks.

can you hear this whine at a neutral coast down?
does it need a load on it and or is it rpm dependent?
i'm thinkin' tranny rear end related. When my rear went bad and whined, it also dragged making it stall pretty easily, but i see you're dying at a stop.
Just something to think about.

i bet you anything its a boost leak is what it sounds like especially since you can here the whirling sound of the turbo...... or it might be the MAF it might have taken a crap on you

is there a way to check if the MAF is working?
also it use to run perfectly then the first time the turbo spooled it ran bad after and had that whirring sound

its rpm dependant when idling it makes no noise
only when coasting in neutral it stalls. other than that even on a stop it stalls but its a really low idle like 500rpm

hmm, maybe cyanideslethlax is right. if its a boost leak, it probably "pipe totally disattached" status, to make it do that.

i had a hose pop off and it did the exact same thing. and made the same sound.

Winner!

And it's probably not the AFM. Check for boost leaks FIRST. My car sounded just like that whirring sound just today when I blew an intercooler hose off. Check the hose coming directly off the turbo. That one take the brunt of the heat, and has the highest probability of being the culprit.

Make a boost leak detector, and check for leaks. There's a link in my build thread, on page #108. I tried to copy and paste the link, but it doesn't work when I put it here.

ok heres the update, i have make a boost leak detector and its leaking from the BOV (i think because i hear it at the BOV ) maybe stuck open, does anyone know how to close the BOV, or should i get a new aftermarket hks kit?
