Rolling coal is one of those idiotic expressions of personal freedom things so beloved by the wingnut peanut gallery and we've got quite enough of that already.
To put it another way, modifying your engine timings and shoving a turbo in there should be legal even though it will probably increase emissions because the intent is to increase power. Modifying your car to increase emissions just because you can is an asshole move.
While people in the car community hate CA’s CARB certs, they exist for a reason. If you can prove that your performance parts don’t increase the emissions, CARB has no issue giving the mfg. a certificate that says it’s legal to sell and use in California.
It’s not hard to make big power in a gas or diesel vehicle and not substantially increase emissions. Hell, Gale Banks has been doing diesel performance for decades and he loathes rolling coal.
