Help with troubleshooting
I'm trying to troubleshoot a problem. Here's the symptoms:
Whooshing/whistling noise starts around 3k rpms and builds with rpms.
If I go to 6k rpms and completely release throttle an air noise similar to a fast and furious blow-off valve purge is made.
The normal pull you feel from the turbos is completely absent.
Noises are worse when car is in gear than when I rev in neutral.
I'm working on this alone and don't have any help. I'm guessing the blow off valve is stuck/broke and needs replacement. Any other ideas before I drop money on a valve and replace it. Thanks in advance for any help.

You don't mention your boost pattern? The stock BOVs rarely fail. Usually it is solenoids or check valves.
