Does anyone know if wastegate arm rattle is a potential performance issue or failure point waiting to happen? My wastegate arm rattles occasionally, and I can't tell if it creates a performance reduction or not. Those who are upgrading their turbos, are your electronic wastegate and recirc valve oem original? My understanding was you couldn't replace those parts separately without buying the whole stock turbo as a unit.
