Ah, nope.133-138 TAS at around 7000 ft depending on the condition of the paint/wax, engine, rigging, and prop.
Perhaps the turbo model can reach that at high altitudes, but I have no experience with them
The reference speeds will be fixed in the next update. Note these haven't changed since release and shouldn't affect the flying experience, just the UI.
