I don't see too many of people using the mods around here.. but are they bad for the motor? If so than why do semi's always puff large amounts of smoke? Why do people wire in switches to cut off their turbo, isnt that bad?! Why why why?!?!
People don't do it because it's stupid and ruins diesels for everyone else. Semis that put out tons of black smoke aren't running correctly, or they're old. Well tuned trucks may put out a puff, but it'll be lighter.
Rolling coal is stupid it's just wasted unburnt fuel a properly tuned truck shouldn't be blowing big smoke clouds.There is nothing wrong with tuners but have it tuned right get your self some custom tunes from a reputable tuner. If you really want to belch black smoke every where don't expect much help on how to do it here but don't forget to cut atleast 1 hole in your bed for a toatally awesome stack too.
douchbaggary. I was watching videos where kids wire up smoke switches to cut off power to their turbo and the check engine light comes on that's probably the first "hey this probably isn't a good idea..."
