No, this isnt another "I WANNA ROLL COAL EVERYWHERE I GO THREAD", but my question is, how many of us actually run a clean or smokeless tune on your trucks? I love the coal when its needed, but why do it all the time? My truck is going in for the EFI live in a few weeks, and I wanting to keep it smokeless as much as possible. Dont see the need in making ppl hate the diesel community just to be cool.

Oh, and let the flaming begin, i know i am gonna hear it talking about not likn gblack smoke on a diesel forum, but oh well

 

No flames from me. I would be happy if my trucks ran clean like a gasser. Id much rather have solid power than blow a bunch of smoke.

People that blow smoke all over the roads are irresponsible and are the primary reason the EPA has cracked down on our much beloved hobby.

 

 

I am actually suprised to see cummins boys say that. Not trying to bash on the CTD. But seriously, it annoys me to see these "bro trucks" blowin coal and never being used as a truck. they might as well drive a car. And its creates all the problems for those of us who actually use our trucks.

 

i noticed a major difference in the amount of smoke after i installed the 4" dp and 4" dual exhaust. the turbo spools up a lot faster with the DP so the smoke clears up a lot sooner.

 

10-4 mine usually only smokes when i forget what gear i pull out in, or if i got a trailer on it.

 

There's no way to "tune" my truck to be inable to smoke; the aftermarket transmission is so tight that at stock power levels the first-to-second shift almost stalls the engine unless I'm around 3,000 RPM.

Also, with an 18.5 cm exhaust housing, 3.07 rear end and three speeds plus overdrive, there are parts in the power band where smoke is impossible to avoid if you find yourself without latent boost and in need of acceleration. If I ever find myself going 30-45 MPH without any boost up a hill, like on a freeway off ramp, a few seconds of smoke while I spool the turbo is unavoidable.

I can usually drive with very minimal smoke, but tuning a mechanical governor for performance without any smoke isn't as simple as flipping switches.

And when it comes to smokeless WOT performance on a 20-year-old relatively-inefficient injection system, it's not going to happen.

I have a DPF in my garage I'm retrofitting onto my truck next time I redo my exhaust, because I hate drawing attention to myself and not being able to play with people stop-light to stop-light without blowing smoke into their windows.

 

Begle- I thought about the old 1st gens after i posted this up. i fugred it would be an argument, and they are different story. they came factory puffing like a freight train. i was more or less referring to the new "clean" diesels that ppl smoke out every intersection that come to.

But there aint nothin wrong with some coal every now and then, just not 24/7. but like you said, being smokeless allows for the stoplight to stoplight action without drawing too much attenton.

 

Stock, no pick-up should smoke if everything's up to par. Mine couldn't smoke under any conditions.

 

i'd figure if you're gettin EFI live, you'd be able to very easily make sure you have no smoke...just turn your off boost fuel down very low...kinda like a stock AFC in a p pump

and yes, smoke for the sake of smoke is retarded
