I see these modern big diesel pickup trucks ROLLING black smoke under acceleration. I mention modern to indicate they aren't old beaters with engine issues. These trucks are tuned to do this...why?

What is this about? Do you really get better performance in a road vehicle doing this? We aren't in a tractor pull on I35 folks.

Oh and the stacks coming out of the bed? Well, those I can live with if you don't emit coal colored plumes of smoke out of them, but still!

They're tuned. Get better power more gas mileage.
But...but...that can't be done without causing my car to then smell terrible and I have to breathe the smoke?

More power for? They aren't pulling yachts uphill or even pulling trailers!

Performance, get an old Corvette or something and put it on a 80's silverado chassis. (whoa, let my roots show there)

Lol I drive a civic.

But today's diesels are programmed from the factory to put more value in what comes outof the tail pipe. That's why you have a nozzle for gas and. Nozzle for 65% water 35% def mixture.

So all those smokers you see out there have flashed the computer and have different fuel ratio and stuff settings to where they have more power (they are fast push you back in your seat fast). And get better 20% sometimes fuel economy.

Some call it "rolling coal" and do so to be idiots and impress people or smoke out the car next to them. Search it on YouTube, they do it to joggers, bikers, walkers, etc.
Others, like some friends, are getting better performance such as acceleration, mpg, etc....just optimizing the ability of their engine....

I dont get it. Pull that stuff on a track or out in the country with no traffic. Im going to have to make it a standing policy not to follow diesel pickups and just breathe the smoke and yell 'Merica if it happens again.

I might have to switch careers, become a cop, write only tickets to these guys. Will have them filled out beforehand.

Lmao haterade? I have no problem with missing, if you read my post...it's the douchebags behind the wheel when they wanna blow smoke in someone's face that it becomes a problem. I used to race against my buddy's megacab when I had my lifted tundra and his truck would shit and 'git.......

Mod it, Hell yes.....be a douche with it, I hope I'm the one to lull them over.

I had Diesel engine classes and they taught us that if a Diesel smokes like that, it's either over fueled or under aired.

I don't understand how it can be more efficient to be blowing black smoke. Its coming from a rich fuel mixture....everytime I see it, I wish they'd get it in the shop and have it checked out.
