my truck is a 19 3500 with 227,000 miles d&t @130,000ish it keeps jerking or chugging or what ever you want to call it when your pulling hills it doesn’t seem like an injector connection this time I hooked my scan tool to it I’m not a mechanic just a farmer with a degree in figuring things out and changing parts the only thing that I noticed that seemed odd is the fuel rail sensor 1 is reading 1.06v key on engine off and number 2 is reading 4v Key on engine off the pressures driving down the road differ at times by 800psi I’m not sure if that’s normal or not or i might be chasing something totally off of where my problem lies but tcc slip hasn’t shown anything more than -11rpm to 7rpm
L5P problems

Being a common L5P issues similar to the LLY, I would guess its injector harness connectors burning up. If you can put a scan tool on and monitor misfires that will give you a good idea.
I had a similar issue and it was a bad MAF sensor.
Saw a truck like you're describing that had a bad air filter. Under load the filter would suck into the intake tube.
