100k, runs like crap

[BFinMO]

2019 Powerstroke, 115k miles.

Just replaced oil, fuel filters & full trans flush.

Looking for some advice. Trying to wager between keeping this truck to pass down to my son, or trading up to a 22/23 or so.

Basically, right after hitting 100k it just runs rough. I dont really know how to describe it. Super laggy turbo spool. Really stinky exhaust, when DPF not full.

It sounds way louder when driving around and when sitting idle there is lots of engine vibration in my feet. When outside the truck while it is idling, there is a slight ‘whine’ sound like a straining power steering pump. Simply, the truck is just not ‘smooth’ anymore.

I have had it in the local performance shop here and they aren't finding anything. We love this truck and Im not really ready to trade, i just want my smooth running truck again.

Anything jump out that could start something I can research? The stinky exhaust really bugs me. Normal load, pulling into driveway, get out and my eyes burn It stinks so bad.

Any thoughts?

How is the boost? Maybe there is a leak in the piping?

I’d look for exhaust leaks as well as boost leaks. As far as the whine goes, see if it does it key on engine off prior to the fuel pump shutting off. Could have an air leak somewhere causing that noise, could also explain the rough running. What all is done to the truck?

The shop said there were no boost codes, and if there was a leak it would throw a code of some kind.

No, the sound is more of a 'whine' that a hiss or something. No sound while the truck is in on, not running. Not Like after a fuel filter change when purging the air out. I was convinced at one point it was something transmission related.?

Like mentioned above, the boost a lot of times is REALLY slow to build. I was pulling 12k lbs the other day, and from a dead stop it took over 8 sec for boost to build so I could get through the dang intersection.

Only thing non-stock is a topper and I have had it since mile 7. I have the opportunity to change that, but, dont really want to invest if there is something bigger I am going to have to fix later. As much as I would hate to, I may just trade up, then mod.

Thanks for the responses!!

Kinda sounds like a tired/stuck vanes turbo. What PSI you see on a hard run??

I questioned that, is that a thing on 6.7's? I maybe see 28-30.

When it does spool, its like there is nothing, then everything.
