Has anyone with a CHT gauge used a thermometer gun to check the accuracy of it? I was just pointing mine at the base of the spark plug on #3 and was only getting upper 200°. But it may have not been totally warmed up yet and it was just idling.

Cheap IR thermometers make some assumptions when calculating temperature that you can't change (emissivity and a few other things). It'd be interesting to see what you read if you painted the end or your spark plug vs. shiney metal since that would bring its optical charactertics closer to most of the assumptions.
