I have set a limit of 400 degrees for CHT, so I have never seen the decrease that follows with higher flight levels. I chicken out first. I will check my cooling air; any improvement there has to help. Tomorrow I will be returning from KFXE (Fort Lauderdale, FL) to KAMA (Amarillo, TX - home town). I'll experiment more during the flight.
