Just started the last couple days, wasn't bad, but it's been getting progressively louder. No abnormalities at idle or low RPM, but as I give it some fuel and the turbo speeds up it gets a whining sound to it until OD kicks in and then it quiets back down. Check the intake box and tube and clamps to make sure they were tight. Not seeing anything to the naked eye that concerns me either. Any ideas on where to begin diagnosing the problem. Recently did a TC lockup switch and bigger tubes
