I wouldn't say 12-15 years. I've seen plenty of 2014 and 2015 powerstrokes with choked intakes. I know the newer ones use less EGR but how much less I'm not sure. I can't speak to the other diesels as I have no experience with them.

 

I would assume use, duty cycle, low speed vs open road all have alot to do with EGR health.

 

So I will admit that I'm still on these forums because my FIL has his 6.7 Powerstroke - I don't actually own any Fords anymore.

BUT, I will add this:

My '22 Cummins uses MUCH less DEF than his '23 Powerstroke. I don't know if it's because I drive longer distances at higher speeds, or if it's just inherent to the programming of the Ford vs Ram systems, but on our last trip together (we camp with them from time to time and live near one another, so distances were almost identical), we both filled up before leaving, then filled up again when we got back...He had to use a jug and a half, so about 3.75 gallons of BlueDEF...I used less than one jug. Our rigs are about the same size and weight too.

Take that for what it's worth I guess.

 

I leave my EZ link plugged in all the time, also there are a lot of emissions intake tunes available now if you are afraid of remove the EGR/DPF. Recent trip back home from Cle Elum WA to Poulsbo WA speeds from 60-75mph I averaged 17mpg.

 

Yep! Use it like a truck is supposed to be used. My 6.0 did lot's of towing and the EGR stayed mostly clean..

 

If you're going to use one of the mass produced for sale delete tunes then yes just get rid of it all so the tune functions as intended. If you were to actually code your own tune you can indeed leave the DPF/regeneration active yet physically do away with and code out the EGR SCR/DEF and DOC function. On the pickup truck the DPF is next in line after the EGR and ahead of the SCR and DOC. The DPF and its regenerative function can work without the other supporting emissions systems ahead or behind, just know whatever is ahead of the DPF and now removed leaves that non recirculated and unfiltered exhaust to hit the DPF and therefore will require regeneration more often.

 

There is an emissions tailpipe standard to meet. There is no mandate on the systems used and in what order or how much/how little use to meet the standard. That is entirely up to the engine manufacturer and not at all the same across the board. Example, Cummins/FPT still use EGR in favor of DEF. Ford as of late decided to use DEF in favor of EGR. Both the same systems targeting the same molecular structures used in different capacity. Many more examples across engine manufacturers some going as far as to redesign their engine lineup for a more efficient fuel burn alleviating the need for certain emissions systems such as SCR, DEF, and DPF allowing for just the use of CCV, EGR, and DOC to meet the epa tailpipe standard.

 

full diet here....24mpg on the freeway doing 60. just was curious if you had any bad luck getting it flashed by the dealer for a normal update.

 

My thoughts for what it’s worth. I used to delete my trucks from brand new because nobody cared and they ran a lot better. Early DPF / DEF systems were very problematic and expensive to fix.
However now like you said. Many shops won’t touch them if they are deleted. Forget about warranty. Also no dealer will take them on trade if they are deleted. Also due to all the EPA fuss, they are typically hard to sell and are worth less money once deleted now. Plus in some states and provinces, if they see you puffing smoke they can pull you over and put you on a tow truck out of the state, or in Canada take you plate and it can’t be registered again until it’s back to stock. In some cases if they find out you had the truck deleted, even after it’s sold and long gone, they can come back on you for having it done also. Also we used to have really good reputable tuners. But now due to the EPA they are gone and I don’t think the quality of delete tuning is what it used to be before either.
So I wouldn’t delete a truck anymore due to these reasons. Just not worth the potential headaches to save a couple bucks on DEF and maintenance IMO. But I sure do miss my 700rwhp twin turbo Duramax I had before I started buying Ford’s. It had a clean tune on it, tons of power and I loved driving it. But times change and I guess I had to change with them, even if I disagree completely with burning more fuel, to reduce soot out the tailpipe. I don’t think the reduced soot makes up for the reduced fuel efficiency and all the carbon that’s generated to get, refine, and truck all the extra fuel we are burning.

 

Today deleting is do it at your own risk which has gone up exponentially in the past 4-5 years with the EPA coming down extremely hard on those selling parts and tunes, and the EPA now has ALL the customer records, which means anyone who bought parts and tunes could someday get a visit if the bumbling fool has his way with green energy. IOW it really is not worth it anymore. The EPA has a web page where people can file complaints. Someone behind you with a dash cam see you roll coal, even if you are not intending to because without the DPF, soot happens, and they can upload that video with your plates to that site and potentially lead to you being contacted.

Then again you could do something completely stupid like put a 12" stack out the bed then roll coal past a cop filling his car at a gas station. Yeah, saw it first hand, the guy lost the truck and more than likely paid out the nose in fines to the state and EPA. It was a county mounty that busted him.

For those of us with COPD or some other form of respiratory illness, we appreciate not getting deleted.

 

20-22 Fords used MUCH less DEF than the 23's do. Ford bumped up the DEF consumption in 23 in favor of less EGR

 

I would happily add a jug of DEF every other fill up as opposed to having EGR.

 

There is no soot or black smoke on stock power level tunes. I only get smoke on level 4 which is 200+hp over stock.

 

A bit off topic as it has nothing to do with warranty work, but I believe people running these “no soot” tunes should keep the DPF installed. Put their money where their mouth is, so to speak. No soot means the DPF wouldn’t plug and they wouldn’t have to worry about regens.

The truth is diesel engines produce more harmful particulates than gas engines even when you can’t see it. And they do affect those with respiratory ailments even with no visible emissions. If they didn’t we wouldn’t have the mandated particulate filters. Automakers could easily meet a “no visible emissions” standard. That’s just not the yardstick, and for good reason.

All that said, if I lived out in the middle of nowhere and was having trouble with the emission system I would consider deleting. As long as mine is working and Ford continues to keep it that way under the emissions warranty I’m leaving it in place.

 

They can’t work on anything at and past the delete pipe. Or at any delete mechanisms under the hood.

Obviously they can’t work on the motor because the tuning wont allow them to hook back up to any delete mechanisms.

They probably can’t properly scan tool it either if something like your transmission goes out.

So you become your warranty shop on a lot of items if you want to start defeating emissions equipment.

I would leave it stock or use an emissions friendly tune you can reverse. They are pretty noisy stock and deleting them can make them obnoxious.
