That's less about removed emissions devices than a "performance" tune. A truck without a DPF isn't going to shit out black smoke unless some yahoo has a tuner that dumps fuel in that doesn't combust fully.
Which they do on purpose just to spite electrical car drivers; rolling coal, climate change isn't real, god is real and HE would never allow that, yadda yadda! Assholes be assholes.
An EGR delete WILL let you push out black smoke on a stock tune, but it won't let you "roll coal" as they call it, it'll only do it if you gas it real hard and even then, it'll just be a puff.
Exactly. You have to really be trying to make a properly tuned engine shit out smoke, or bad rings. Detuning for power is what smokes, and then you have these chucklefucks that specifically set up the engine to roll coal. I think people that do that should be put in a sealed room with a hose to the exhaust of their rigs and someone revs it until the fuel tank is empty.
