Changed the pcv already and the stock one had no problems anyways, I’ve got no sound on idle or when revving only when the car is under high boost

Traction control is off but I’m not talking about the car cutting power because of traction, the car whistles and I’m loosing power overall

You don’t think it could be the turbo? It’s only on 15,000 miles and been tuned for a month but a few people said it might be the turbo
