Thanks Lead Balloon. I plan on reading that article in detail this weekend. Yes, I'm seeing plus 400 with full rich. Ignorantly I have not been monitoring this closely so cannot say for how long or exactly how high I have seen this. Will definitely be paying attention now. Again, in training it was ful throttle, full rich and away you go until you reach altitude. As I now have a new digital CHT to compliment my old dial I am seeing more accurate read outs I guess. The old dial one never gets too close to the red.
