This may be because they couldn't maintain 400Nm from low RPMs and still make the engine reliable enough for track racing, so torque limiting at lower RPMs was necessary (not that it would matter on the track but it does matter on the street). Or maybe the larger turbos cannot provide the necessary pressure at lower RPMs.
nope, they say that the full 550nm are available between 1.850 and 5.500 RPM.
