Make my 6.7L roll some coal please!

[Spruce Goose]

Ok...
I've done all the stuff in my sig and was hoping that running on the 60hp tune i would at least see SOME coal rolling after I stomp on the throttle having been stop and go in the city for a while.
guess what... NOTHING!!! lol
My 06 with the 5.9L rolled at least a little bit with the smarty on the 70hp. Whats going on here? I'm hesitant to use the higher settings on the XRT for fear of my tranny not liking it, plus no studs or anything. I'm just looking to have a little coal roll once in a while and didn't know if there was anything else I could do other than run the tune up anymore

It's amazing the hostility people get when they ask this question, when everyone of us at one point asked this very same question. Why not for once y'all try to answer this question with out a smart*ss attitude and stop giving the forum that reputation.

wouldn't catch me trying to roll coal in the city, to much traffic the guy behind me might get out his car and kick my face in

[Spruce Goose]

WOW!

Not sure what to say
Just wondering about a simple question and it seems like I fell into the lions den with a bunch of steaks strapped to my waist.


Do me a favor though... Next time you want to Sh!t all over my thread try to resist

Asking us how to "Roll Coal" is like asking a Green Piece Hipppy to pour a barrel of oil into the Gulf of Mexico.

Just not a good subject at all to ask about. Nobody wants it and it is an unfortunate byproduct of making power with a diesel. But with the right parts and better tuning offered today it is helping to clean up the tail pipe.

Here is the best part... I NEVER said anything about wanting to just go around blowing smoke all over the place. Maybe if someone would have engaged my question a little further i would have had a chance to explain that i just find it a little odd that my truck wont even clean out the tail pipe when excellerating hard even if i just put 500 or so miles of city driving on it when my 06 would. Maybe it would have just been a lot easier if instead of everyone piling on me like a group of highschool girls someone would have just asked me to maybe elaborate a bit more?? Dunno, but I am willing to bet this is exactly the kind of BS that makes users who have been on here for several years like myself that have recommended this forum to others, supported its vendors, and even praised it for being a good resource for info decide to say screw it. Hey, maybe im wrong though and this is the kind of site that the admins want cumminsforum to become and ive been completely wrong all these years?

now now guys, threads gettin outta hand. were better than this, yes every freakin newb gets on here asking how to roll coal is annoying as helll but still doesnt justify us to act like complete retards. to the OP, use the SEARCH BUTTON!! you might learn a thing or 2. 6.7's have plenty of fueling as it is, not gna see much activity out of the tail pipe until you start messing around with your CP3, injectors, and charger setups. they were designed to be an efficient motor out of factory, gotta get rid off all emisions and that crappy VGT turbo

[Spruce Goose]

Now was that so hard?

/Thread jack time
Why don't fully deleted 6.7's puff black smoke? I am just curious really, I kinda like driving around without worrying about blowing a smog cloud everywhere regardless of how I drive.

I guess what I was really wondering was if the 6.7L is just doing that much of a better job than my 5.9l was as far as efficiency goes on a mild tune or is it the XRT is that much better than my smarty was, or is it possibly a combination of both?
OR, if this isn't the case with anyone else with a similar setup running a similar tune is there maybe an issue somewhere in my fuel system that's not delivering the volume I need?
Mains hit it right on the head. I just find it kind of weird that they would even bother putting a DPF on these things if I can't get it to make any soot if I tryed.

you bought the wrong truck if you wanna roll coal. the 6.7's injection system is the most efficient to date. . .it'd be stupid to wanna roll coal with it. that bein said, i'd be happy i have a clean burning efficient truck. i hate seein smoke come outta mine.

How about a smoke switch just my opinion http://www.cumminsforum.com/forum/6-...tch-6-7-a.html
