So i took my car into the dealer to get the boost gauge replaced. After they returned the car to me because they dint have the part I notice this loud blowing sound coming from the turbo. Its best hurt when all the windows are closed inside the car. I dont think its a leak because there is no powerloss when i slam on it. I dont know for sure because the boost gauge is messed up so i dont know how much psi im at, but it seems fine. Anyone have any ideas what this sound might be?????? It only comes when im boosting 2.
