Sounds like I should try turning the heat down too, might end up cooking for a bit longer but that's fine.
I would definitely be moving in this direction. I used to cook super hot too.
Things like garlic would brown then burn in a few seconds, now I use much more moderate heat and garlic is a fairly good indicator of heat management. Also, there is a fair amount of natural sugar in foods, plus what marinades and sauces add, those things burn at relatively low temperatures.
