Low side governor failure, P3 air leakage?
P3 Air issue should result in hung start. But I guess you are referring to Pressure governing, ie the line running along the top of engine to the power turbine part of the CSU. Have experienced leakage here on a Caravan engine which resulted in topping out at about 1680 RPM.
This should show up on preflight run up.
