Subject: TIT vs. EGT, strange but true

I have noticed a strange but reproducible issue with my TIT's (see EIS issues.pdf).  In cruise and with a steady state power setting (EGT's, fuel flow, fuel pressure, man. pressure, rpm all constant), the TIT's climb over 50 degree F over a 1 hour period.  They eventually reach 1650 degrees F and the alarms start to go off.  I richen the mixture to keep the temperature below the recommend 1650.  Once the mixture is richened and the TIT's fall below 1650, the TIT's do not continue to rise for the remainder of the flight.

 

I would like to start flying LOP but the TIT rise makes the issue a little confusing.

 

Anyone want to take a shot at this mystery?
