Diesel truck emissions have been reduced by 90% since 2000. Unfortunately some people have a burning desire to roll coal and they cut off the DPF and reprogram the computer with a "tune" to dump more fuel during the combustion cycle. All of this of course kills fuel economy and power but they feel the power band shift and think it helped...and they get to blow black smoke on people. So if you see someone rolling coal, know that they modified their truck on purpose to do that.
- SoftTalker 3y agoYeah they are idiots, but fortunately in the big picture there are not enough of them to really move the needle.
- hedora 3y agoI’m not sure about that. I once watched an idiot roll coal across an entire state on the freeway (the rest of us drivers were not amused). They clearly were producing >> 1000x more particulates than the rest of the vehicles I saw that day, combined. I’d guess that one car was pumping out 1,000,000x more crap per mile than a non-modified car.
