I agree, but when you have a F'n gauge telling you that your EGTs are way too high, you let off. EGTs typically go up if you don't have enough flow mods when you have excessive smoke. That's all i'm sayin. If you don't have an EGT gauge and you see crap loads of black smoke, you are better off to back off the throttle. If you have a gauge and still are in a decent range, your fine. But, if his engine melted down, he had high EGTs which means someone is a dumbass or didn't care about whineys truck. You can produce all the black smoke you want if you can get rid of the heat quick enough.
