With the TST and Edge stacked. How much black smoke is there? I'm one of the few out there that could care less if my truck dumps black smoke or not. Either way I live in CA and have to be careful. My TST use to smoke quit a bit when I'd get on it. But since they reprogrammed it it's better. But by adding a pressure box on top, I'd think it would dump. Also, what type of temp drops am I looking at? I can smoke on 7/7 when I get on it. But it's not that super black soot coming out. It's more of a dark haze that comes out for a second or two. I don't want to have to be carefull everytime I get in the truck.
