Help - Weird Screeching Noise under boost conditions
Hi....
My car has developed a screeching like sound when under full throttle and it seems to be misfiring/starving within 500 rpm of redline. Never had a problem before...this started yesterday while driving home on a road trip.
The boost feels fine except for the misfiring close to redline.
The noise is at all rpm above around 3000 and constant.
I was showing a friend my DV before this happened and just barely nudged the thing with my finger - could this be the problem?
I don't think it's the 'Revo screetch' as I never had the problem before in a few thousand miles of Revo'ing.
WHAT DO YOU THINK?

Tightened all DV hoses - no change
It seems to be a faint screech accompanying the turbo whine - anybody think it could be my turbo bearings?
I'm also going to run the tank down and refill - I'm wondering if I got some bad gas (please, no jokes) and that maybe I'm hearing some 'pinging.'
Any thoughts appreciated.
