I claim no specific knowledge about your situation but would like to ask a few questions. You mentioned "delete" so I assume you removed the DPF. What did you do with the sensors, specifically the pressure differential sensor that is on the DPF? Do your "tunes" specifically address these sensors as part of the install? Can you correlate the message specifically with the removal of the DPF or did you do all the work at the same time (DPF removal, software, EGR)? My thought is that lacking the proper signal from one or all the sensors the truck thinks the DPF is clogged or has a hole in it. If you aren't getting some sort of "Drive to Clean" message, I am thinking the latter is more likely. Just a thought....
FORScan for dash light issue after delete
I am getting the attached message notification at every start up after delete. It also does an annoying do-do do-do do-do chime. Once I hit ‘okay’ the messsage does not come back until next start up.
I have experienced this with two different tuner’s programs. Anyway to shut off in forscan?
Thanks!

Correct on delete. All the sensors are still hooked to the truck and zip tied up to the frame. I went through a few different tunes. The first tune would not (and still does not) display this warning in the message center at start up. The issue with that tune is that the truck smoked excessively. I have tunes from two other companies which this message displays at start up.I claim no specific knowledge about your situation but would like to ask a few questions.

Since one of my 3 tunes does not do this, I am sure it can be shut off. My third tuning company is awesome. Only thing I do not like is the message. They have tried multiple times to help and are unable to correct. They also do not see this issue with same tune on other trucks. They have been great to work with, just at a loss as to how to fix.
I appreciate the conversation and your time! Here is what I theorize.......
White smoke when cold is normal for “Old School” diesels. My 07 Dodge would puff when it was cold but because it had an ECM, it would correct the rich and stop. Part of the correction was the ‘hair drier’ would cycle on and off below 1500 rpm until the engine warmed up. The lovely sweet smell of rich diesel is just part of the package. As you surmised in another post, it is all a product of too rich for the cylinder temp. My guess is that your first tune was an off-road, generic tune with no cold start correction. Did you tend to “Roll Some Coal” when you jumped on it? I also guess that it had all the codes to turn off anything having to do with the DPF/DEF system. I am wondering if the next two tunes you had were written for trucks with their emissions systems intact. This might explain the lack of smoke and the messages. As the EPA is supposedly cracking down on these sins of omission, I suspect more tuning is down systems intact. This isn’t all bad in my opinion as it makes it harder for manufactures to argue that vehicles were over tuned. I have thought about going down this road but I would settle for a simple remap that gets me 50-75 more pounds of torque,15% more mpg and control over the regens.

All the tunes I have tried are for no emissions on the truck. Each had their own little settings like unplugging EGR valve and/or other things under the hood.I appreciate the conversation and your time! Here is what I theorize.......

First tune ran good but smoked like crazy. Start up anything under 120 degrees engine temp white smoked bad. I am talking smoke people out in parking lot. This also stunk!!! Not just the normal diesel smell. No black smoke at WOT.
Tuning company 2 - smoke was greatly reduced. Like you said it had better low engine temp fuel curves. Black smoke at WOT. Issues where a click click click on the 2 to 3 shift and 3 to 4. I thought it may continue but Road noice was getting louder. Second issue was the dash cluster start up warning.
Third tuning company -puff of white smoke at cold start and goes away pretty quickly. Like 50 degree temps goes away in seconds. Black smoke real nice at WOT. At first I had the same trans click click click but they sent me a second set of tunes and it went away. I am still curious what that was. I can only discribe it as a much softer sound of a park pin trying to catch when a car is still moving...on an older car. No shutter feeling, only the sound. Only issue, start up light and very annoying chime with every single start up.
