Hello people, I have a 2.3 turbo 9000 Carlsson and under hard acceleration the turbo makes a different noise kind of like a whistling or buzzing but only does it when you give it bit of a caining also this is with a new turbo too,
the noise was the same on the old turbo as well.
Has anybody else experienced this problem?

Any advice is much appreciated.
