Stutter Sound?
I'm getting a weird stutter sound during accel and decel to/from high rpms. It's coming from the area of the dbb turbo, but when I removed intake pipe to check turbo, it spun fine and was tight with no shaft play or scraping of any kind!:

First video=compression surge, I have no doubt, I hear nothing in the second video except something that sounds loose down on the firewall. FWIW I have never heard anything called wastegate chatter either.....Compressor surge is where under decel your BOV isn't venting 100% of the pressure that it should so it has to escape back through the compressor wheel.
