Earlier this week i went to tampa. i did about 115-120mph there and about the same back. I now have a weird whistling noise coming from my turbo area when i 4th or 5th gear. It only does the whistle noise while on the gas, but its not the normal spooling noise. My car is a 2002 w 50k on it could it be the turbo or is there another possible cause for the wierd nosie. Someone please help.
