Hi Guys, So Posting this on behalf of my good buddy, he spent wayyyyyyyy tooo much money figuring this problem out for me not to summarize and post something.
-4th Gen 2010 Ram 2500 Bighorn
Background - So While the truck was still under factory warranty, there was almost no issues or gremlins with the powertrain. After the warranty ran out, my buddy ordered an EGR, and DPF delete kit. Then he followed up with the Mini Max, and that's where the problem started.
The issue - After the mini maxx, the truck ran all around great, but after a few months there was an intermittent stutter coming to a stop.
What did not fix the truck - Replaced CP3, Injectors, headgasket (ARP Studs), Fan Clutch, Cummins ECU, Ram PCM, and an array of MaP, Crank, and cam sensors.
The Final fix - It appears the factory ram fuel system cannot handle any aftermarket demand, so a FASS titanium system was the final resolution for this wallet draining frustration.
