Exhaust manifold temperature...clarification please

[JMBT]

Rawze, you have seen my truck and it's condition at the miles it has and you have seen my EC-M history, so you KNOW, I don't do any super trucking either! Nearly every mile on my truck has been logged at 1450 rpm and 62 mph! I just got confused and a little worried when I read about the damage caused if temps are to low, and I misunderstood that was only information for use in tuning, that's all. It is all Easy-peasy- lemon squeezey, now that I know that one extra piece of info I was missing!
