I had this really bad whine/siren noise for a while also except the noise was there during spool and whilst on full boost.
Started out fairly quiet and then gradually got louder as time went on. Turned out I had a leak between the exhaust manifold and the turbo where one of the bolts had lossened off.
I'd go through all possible areas where a boost leak could be to start with. E.g intercooler pipes, BOV. Could be just a simple boost leak.
