Boost squeak
Recently my car has started a squeaking sound under boost. It sounds like someone pulling the neck of a balloon and letting the air squeak out. I don't really know where to start. It still has the same 10-8-10 boost pattern, just the sound is driving me crazy!

The blow-off valve only vents when you let off the gas.
You've either got a very small boost leak somewhere that is causing the noise (your turbo system will try to compensate for the loss, thus you'll still get a 10-8-10 boost pattern if it's small enough), or possibly a problem with the turbos.
