thanks bmxpunk I'll take a look at that.
rexyrex, If it were merely the 'turbo spooling' faster I wouldn't mind, but it is an ungodly high pitched mechanical whine. Unless during the first 4 years I owned the car the turbo never spooled up when I went WOT. I know when the turbo is fully spooled there is a mechanical whir, but whenever I hit 3000 rpm these days its like having a constant blow off valve sound but higher pitched and constantly increasing until I hit the redline.
