This is not really true just because its deleted dies not mean it has to be loud or blow black smoke i will be deleting mine but keeping a stock HP tune and running a muffler… i just prefer not having dirty EGR gasses causing buildup in my engine and i also prefer not having DEF issues in the cold if i can find a tuner who can delete the EGR and DEF but keep the DPF i would totally do it atleast until i start having DPF issues then delete that too as i have no interest in paying 4k for a stock DPF system

All my underhood systems are intact and still plugged in. Their functions are controlled by the tune. Without the DPF your DEF system is inoperable, but I have left it intact as well. Even on my 150hp setting with the SOTF, I have zero smoke which is of utmost importance to me when towing a new, freshly released from the mold white boat hull. Well, the added 2-3mpg is really the most important... and not having any issues lately is up there.

Try earning your living with your truck and being sidelined for two days when three different Dealers cannot fix an issue related to simply getting badly contaminated fuel, yet the ECU codes run the Dealer's Diesel Techs down the wrong rabbit hole. When you are losing $1000-1500 per day, you will see why "Pay To Play" is really "invested to earn."

I am all for having a clean truck with zero smoke. I have mine tuned for the power and reliability with zero visible smoke... yet so far have had no more issues in 10,000 miles. I also added a high volume muffler, staying with the 4" piping to keep my interior sound level as close to stock as possible. Only when I roll down the windows can I hear any difference in sound.

At any given time, your truck could be down for any 100 reasons. Water Pump, Turbo, contaminated fuel, faulty battery, damaged thermostat, anything. I have had 40,000 trouble free miles mainly pulling 16000 # with it being all stock. I feel most issues owners have is by not keeping it properly maintained or serviced, it can cause several issues either internal problems or external issues.

Idk why you think you need to explain this to mean i know how it works and you clearly cant read because i said i want to keep the DPF not the DEF…… i find it hard to belive you are the only one who has no smoke on the 150 tune it may not be much but i guarantee it does have some smoke

Agreed.

Any of the reasons you listed, I can buy the parts locally for an instant remedy. In six years, this is the first truck I have ever had any issues with and now that it is a truck I own versus leasing, the responsibility falls upon me to have a quick remedy over waiting for a dealer or simply grabbing another from the rental fleet.

In all my research, the issues facing us on these trucks are typically created by something simple but they impact something that has catastrophic related failures. I have started with building a fuel polishing system, it has proven to keep my rear lift-pump filter extremely clean in the past 10,000 miles... and no more issues.

I saw that you want to keep the DPF, but without a means of cleaning the soot from the DPF & SCR, you will have to keep the DEF system. You can turn off the EGR, which I have tried through the tuning while having the DPF system intact, but you will still need DEF. One has to have the other... that is all I was saying.

I intend to make a video this week showing sound levels of my interior/exterior and any smoke if present. I have been hauling in this configuration for 10K miles and not seen any visible signs of smoke. I also seem to have chosen a great EZlynk tuner which seems to rare from the issues I read others are having with the HO/Aisin combo.

Fuel is used to burn soot off the DPF.

I believe there's a tune out there that is simply a DEF delete with power gains. I don't recall who does it, I think it's a shadetree tuner.

DEF has Nothing to do with cleaning the DPF or the DPF period. There are tunes out there that disable the DEF and EGR but keep the DPF in place and regening.

Lmao you should do some research DEF only Lowers NOX in the SCR after the DPF nothing more, hell they had DPF systems without DEF long ago…dodge /cummins started 07.5 (could have been 08) with the 6.7 having EGR and DPF only

Exactly the reason I got the gasser. It’s old technology that I have a chance of fixing in a parking lot, no limp mode BS, and tows better than my old Cummins did. Of course I also don’t need to tow an obscene amount.

Also didn’t want to get a diesel and have to go through all the BS of trying to simplify it by deleting. No matter what you do, aftermarket modifications always impact something else down the line and potentially complicate issues with other systems. Stock is best IMHO. Stock works.
 
The 5mph limp mode is a reason why I consider deleting. That rule is just "forcing" me to do it at some point. I can not even imagine what trouble I am going through when I am on a 150+ mile trip and something fails. One of many emission sensor fails, DEF heater fails, DEF pump fails, etc. The hassle, money and no dealer around, towing truck, trailer, ordering the repair parts, I have not enough fantasy to fully draw a picture.
I like clean emissions and the power tq my cummins has is awesome but the 5mph limp mode is a killer- it needs to go......

I do need my truck to earn a living. I also know that no matter what you do or how much preventative maintenance is performed that something will go wrong eventually. Its good to have a backup; if downtime cost you between $1000-$1500 a day I would make sure I had a solid contingency plan. Delete or no delete something will eventually sideline you.
 
I was having emissions issues right out of the gate. having one of the 1st new ones I figured maybe I'd have to deal with that. after the first 3wk stint at the dealer for issues, I called jenny craig. she did wonders for the truck and haven't had an issue in 33k miles. I understand warranty work, but I can't be down for wks at a time for a knot headed tech to "maybe" figure out the issue.
 
Well someone send me directions to the area to acquire everything for a 2022.

Thats one of the big reasons for me to delete there are plenty of times ill be way out down logging roads hunting if the truck decides to go in limp mode there is no reception it would take me forever to get out to cell service to call a tow truck
 
^same here. I venture out to no man's lands multiple times a year. it would be a serious issue if it went to limp mode lol

this type of situation gets me thinking about the jeep gladdy's with the diesel option... slow speed overlanding seems like a curse to the dpf.. we'll see.

I can share the contacts for what you need... I just posted a video to my YouTube channel with the differences between Jenny Craig's weight loss programs for 2018-2020 and the >2021 HO trucks. I cannot speak for the 2022 trucks, but my guess is the same updates for ease of maintenance has been performed on the >2021 Cummins platforms.
