i dont know, this whistling sound does not sound right. i wonder if it is a boost leak? i remember when i first purchased the car it did not have that sound. after the installation of the forge intercooler, afe intake and er chargepipe with the bov, that sound then appeared. the sound is coming from the left rear side of the engine. i keep wondering what it could be.
