Default P120 "over-rpm"

I'm new to turbines. My P120 that I recently picked up seems to start just fine but during the warm up process or perhaps just after it the turbine then revs up without any command to do so. Maximum RPM is set to 70,000 and has caused the engine to shut off on both occasions that I've started it. The manual states that during warm up the turbine will only reach approximately 55,000 RPM. No transmitter has yet been used to start it, only the GSU. Is this normal? Shall I just increase the Maximum RPM limit?

Thanks,
Dan

It says 70000 rpm for maximum rpm within the limits menu. "Last MaxRPM" within the info menu reads just over 70000 rpm from what I recall. I believe the ecu is version 6.1.

Well a P-120 max RPM should be maybe 123K, so I would start there.
