Message not possible to pull all the way to the redline with these turbos primarily due their smallish compressor size.

At the same preset boost pressure, as the rpm increases, the engine flow demand increases linearly. But the smallish turbos can not keep up. As the flow of the turbo move to the right on the compressor map, the compressor efficiency falls off quickly as it moves closer to the compressor choke area.
