Full de-mandate on a 15 litre Cummins

[Fleetman13]

I’ve got a 2017 cm2350 15 liter Cummins I’m wanting to de-mandate in a peterbuilt wrecker. It went to Rush truck for a recall and they did some tuning on it and it has been a turd ever since. Used to be a stout truck and it only has 30k miles on it. It’s on its second DPF in the last 2 years. Cummins trouble tree literally says to replace particulate matter sensor and if that don’t fix it replace the DPF, this makes 2 DPF and 2 particulate sensors and I’m not keen on putting another DPF on the truck if they are gonna cost me almost 7k a pop. I’ve went in and adjusted the regen parameters (I have insite with fleet counts and such) to enable temp stabilization and to drop the regen speed to 1mph looking for a solution and only thing that comes to mind is de-mandating the truck I don’t want any power gains I wanna stock truck de-mandated. It has set a 2692 (Cummins fault code for DPF system data erratic. Ran the deposit clean and everything passes air handling test whole 9 yards in at a loss. I had a friend come across this issue years ago in a trash truck and Cummins made him fleet calibrate it to a fire truck ECM code. He says it never came back for years. I have the capability to do so just not crazy about putting a bandaid on a bullet hole so to speak. IMO anything that eats its own crap ain’t worth havin
