Turbos on diesels are generally designed to help out efficiency and power, so staying on boost isn't a bad thing per say. Some, such as variable vane turbos, can make boost at with very little exhaust flow. I think a pressure wave supercharger is similar, but I'm not sure which one has better overall efficiency.
