BTW, don't you expect that the CHT would go up during a hill climb, just as it would go down as you head back into the valley?

Transmountain road here in El Paso is a steady climb over several miles. My cht gets to 400F at the top of the hill on a hot day. That is where I shut off.

Down hill is 330F and cruise temp depends on ambient 350-370F. Of course, this is for the hottest cylinder which is #2.

Want to reduce cht by about 20F through richening the mixture at partial throttle.

Oil temp and air intake temp is kept very cool with the coolers, intercoolers, and fans that I have installed.
