Its that turbo chuffing that you described that is an issue. Is the turbo still cuffing a lot?

And then you said.....

Turbo isn’t cuffing. Turbo is original.

I'm confused...... what problem are we trying to solve here if the turbo chuff is now gone??

those 2350's estimate the amount of CAC restriction, CAC efficiency, etc ... and that aftergarbage CAC may or may not be screwing with that engine .. they have a history of doing bad things that have been seen around here. Putting the OEM unit back on would be one more thing to eliminate whenever things are not acting quite right.

also check that the feed-line going to the exhaust pressure sensor is not clogged up.. and replace the IMAP sensor. You said you cleaned it in your first post, but did not replace it. -It cannot be cleaned properly... they need to be replaced when they get old.

lastly, have you replaced the egr pressure sensor?

It’s going on on Monday. Going to have them change sensors on the dpf. Some days it runs great, pulls hills great. Then hours later it will be a turd. I’m getting a new truck within the next couple months with a paccrap. So as long as it makes it that long

So essentially your saying that your destined to make all the same mistakes of the past with the next one instead making what you already have work for you .. and running off to the stealers$its again. - Must be nice to have all the spare moneys laying around to perpetually lease like that, neglect it till all the plague of CEL lights catches up to it, and then dump so that it can be rinsed and repeated.

- what a business plan.

As mentioned before, I don’t own the truck. I’ve exhausted many hours working on it myself. I could pull the dpf myself or take it to Peterbilt by my house. So instead of being stuck at our shop that’s 3 hrs from home, I chose to let the dealer do the maintenance so I could spend time with my 6 yo daughter. I already take care of it as if it was mine. And am by no means wanting to give up on it. But there becomes a point when you don’t own something, time, and money lost from tinkering. I got the truck and it was neglected, I have done a few egr tuneups, changed the doc and dpf, all the sensors mainly on my own as a driver. I do most of the maintenance.
It’s also a carhauler, so it’s beneficial getting a newer truck due to the trailer and rack starts to become a money pit and just worn out.
This truck isn’t getting sold. It just gets another driver in our small fleet.

You should shoot the owner of this truck this thread... You sound like a guy I would want in my employ if I still owned a few trucks. You are a rare bird sir. Hat's off to you. ;-)
