Excessive smoke
Smokes more than my 06 5.9 with 100hp added. Smokes when I ease in to accelerator really puffs when i get down on it. You can see a small amount of smoke just ideling thru the neighborhood. Acts like it is either getting to much fuel or not enough air. I don't know to much about the EGR on the 6.7. I thought this may could be the problem.
Trying to do a regen cycle with no DPF might exhibit those symptoms. I'd expect to get the "see dealer" popup pretty soon. I think you need to do both deletes. Somebody who owns a 6.7 and has done the deletes properly should be able to provide more details/factual information.
I know that we have had issues with the dpf r kits. With the truck still trying to regen and stuff. It would be interesting to see if you knew someone with a mini maxx to try that. and take the dpf r off and plug the mini maxx in
From what I have read, you need to make sure you are doing the key cycle (10 or 15 seconds .. something like that) at least every couple hundred miles. I have also heard that the EGR valves can get stuck open and cause the truck to smoke really heavy. Doesn't seem likely on a 2010 truck but who knows. Another thing I read was that sometimes the black box that plugs into the OBD2 port can sometimes have problems and doesn't reset a regen counter and can cause the truck to go into regen ... might be that. Personally I would just give their tech department a call. I read some reviews on their site and they seem to be able to work out many of the problem people encounter.
From what I experienced on my 08 its the EGR. I did the delete w/Smarty and kept the EGR and it would roll random coal here and there on a small setting like SW3. I ditched the EGR and no more random coal. It would roll on the highway, no load 65mph on a 8 hr trip, just here and there all of suddon.
