Could that be from high EGT's, if so then my engine is probably going south. On some of these hills in cruise I'm getting worse about kicking the cruise off. I keep thinking, I'm almost to the top while the temp is getting up to 1400*. Its still running great but I'm getting mad at myself for getting lazy about kicking off the cruise.
