Makes you think.
From now on, I'm not going to worry about my EGT.

I think there is a failure in that line of reasoning. We should still worry about egt's. The problem is that the pressures in a diesel engine are far higher than the pressures in a gasoline engine. The EGT is measured after the gases in the compression chamber have already expanded and cooled down. The temperatures in the combustion chamber of a diesel engine are going to be significantly higher than the temperatures in a gasoline engine even though the temperatures of the gases in the exhaust manifold are the same simply as a consequence of the higher pressures.
Perhaps there is a physicist aboard the forum who could extrapolate backwards from the EGT's to the combustion chamber temperature differences based on the different pressures in gas and diesel engines.
