Hissing From Turbos
Hey guys(and ladies), wanted to know if anyone has experienced a hissing sound from there 996TT under boost? I just noticed it a little while ago and have no clue what it could be. Any help would be GREAT!

Oh-the car is bone stock. No upgrades.

Yes, I did when I had a leak. The hose on top of the IC was my culprit.

It started about 100 miles ago. It's not a spooling sound, hissing is the best way I can put it.
