The vacuum line that connects the turbo to the boost solenoid fell off one day and i ended up reattaching and clamping it properly. However since that day ive been getting a whistling sound (same sound when line fell off) @ around 15 psi on partial throttle. On full throttle idk if its still happening because all i hear is my EWG. Any ideas on what the sound is? I rechecked the line recently and its on there good.
