Maybe the OP knows about these problems and has found an online solution??? I don't know if the DPF delete is the solution or not; beyond my knowledge. I do know that I have driven tens of thousands of miles with DPF and DEF injection system on my Ford truck for several years and now on my motorhome with a Cummins engine without a single problem with those systems. On my vehicles, the pollution control system works as advertised. The engines are designed with the exhaust system and resistances in mind. It works real good and keeping the air clean without any black smoke. I would be very nervous to remove components that are part of the critical engine design, and then expect it to operate properly on either of my vehicles. That said, maybe his engine is a problem and there might be a work around to get it to function properly. I wish him luck.

We purchased an extended warranty through camping world, it does not cover anything dealing with exhaust filters. International Garage says this DPF filter could not be cleaned has to be replaced for $5000. We are trying to clean the fuel system now with Diesel additives. Hope it works. We have only 51000 miles on engine, not done any extensive idling.

Well probably pay it off in a year or so and sell it for something different at that time.

I contacted the shop im taking coach to next month. They said that there is some vehicles they can not delete but mine sounds like it can be as it does not have DEF. He did say that IF the shop said yes there has been modifications to the exhaust warranty may not cover BUT not only does warranty normally not cover exhaust but they are not going to relinquish any extra information to the warranty place and nobody is gonna come check to see for themselves.

But that doesnt mean another shop would mention it so if im out and about and get stranded there is risk unless I tote the old one around and just change it out if need be...

I deal with warranty all the time. I always tell them that it broke due to age and usage. No matter what.

How much was the warranty? If you’re only gonna keep it for a year or two, cancel it, get your money back, delete the DPF professionally.

It may run so much better afterword that you’ll decide to keep it. I had a friend delete the 6.0 diesel in his Ford and it ran great after.

warranty was 8k and only for 3 years. We hadnt planned on only keeping it for a short time but this engine part wasnt planned either so it has certainly brought on a different train of thought.

Hadnt crossed my mind to cancel warranty. but actually i didnt know that we could so this is good information to seriously ponder.

We made it to our destination. No engine codes or regen light.

I got scan gauge hooked up for trip out.

Can't remember but pretty sure I read some threads on maxxforce 7 turbo boost psi being so we here around 22ish???!!!!

I never got over 16psi at any part of the trip here, considering scan gauge is right.

Can anybody confirm on turbo boost psi?

Boost pressures on a diesel are usually fairly high. I wouldn’t think that 22psi is outside the realm of possibility. Modern diesels are designed to be turbocharged from the outset.

Also, $8,000 for a 3 year warranty seems insane.
