Looking for options and actual owners that have fallen victim to this. I keep hearing about CP4 catastrophic failures, and have yet to meet someone on a forum that has had the $9K+ bill (always been a friend of a friend). My 2016 is factory(ish) with a Banks CAI, FASS LP, CAT 2 micron filter upgrade, BD water separator. I use a fuel additive every fill up and the truck has 56k miles The majority of them are towing 9K or more. Now that there’s CP3 conversions that keeps my truck in emissions compliance, this is tempting. However, the CP3 isn’t bulletproof either. I had one fail on my CR 5.9L Cummins before 80k miles. I was looking at the Industrial Injection CP3 kit for around 1750.00. Any other recommendations?

bought a 2015 gmc 2500hd duramax thinking I was buying a good truck boy was I wrong. started with the def heater failure and now the injector pump failed. been in the shop for almost 3 weeks now. dealer replaced everything as there was only 80,000 miles on the truck. picked it up last Thursday after dealer told me everything was done drove it 500ft and truck died again and wouldn't start. i talked to the shop forman while they worked on the truck and he told me it was not a matter of if it will happen again but when. That is not very comforting to know. I was just lucky this happened to me at home and not when I was traveling towing my camper as it could have put my family and I in a very unsafe condition as we camp in the mountains. hopefully GM will fix the situation but im not counting on it.
