DSM guys can keep me honest here, because its been a few years, but isn't the OEM boost gauge simply controlled by the ECU based on estimates rather then air pressure? A malfunctioning gauge in your cluster (I won't even refer to it as a boost gauge) can be caused by something other then a "broken turbo."
