Hi again

Sorry NutLoose you are probably right. It is a PT6-28 on a Beech E-90.

Also got my facts a bit twisted. Redlines at 100 and 60. Green arc from 100 to 80. And we are constantly indicating about 60/65 to 80. As I said still within red lines but outside of green arc.

After a couple of talks with our AMO I also found out what the problem is. The wires coming out of the pressure sensor are too close to a strut of the engine mounting. After a repair and a couple of hours flying, the vibration breaks the strands inside the wire and we get a dodgy indication in the cockpit. Once the plug and wires get fixed/replaced we are good again for a couple of hours.

The matter is just extremely frustating...

Any ideas or quick fixes I could relay to our engineers ....?
