My dream is to one day to find a low mileage KJ CRD in a barn and I would sell my replacement vehicle in a heartbeat!

55k low enough?

Possibly, what does it look like? It have to be under 25k miles for me to seriously consider it. 55k is when all of the little stuff started happening like flow control valve failure, glow plugs, wheel sensor wiring with intermittent faults, cooling fan going out, thermostat failure, etc...etc...etc..

I'm driving a Hyundai Santa Fe Sport with the 2.0 turbo engine. It gets better fuel economy then the KJ CRD and is able to hold 75mph going up Vail Pass. It is rated to tow 3,500 lbs which is plenty enough for my aluminum trailer with 2 Poo sleds, between 1800 and 2000 lbs total. Since its a Hyundai, my kid brother who is very car smart, stated I got rid of a lemon only to replace it with another lemon.

I've already put over 3k miles on the Santa Fe and am liking it more each time I drive it. I offroad in UTVs so don't need a vehicle that does that but the Santa Fe does have a diff lock and hill descent control.

Don't worry about me, I still have an 07 WK CRD and an F350 SCrew Cab with 8' bed as oil burners. BTW, if you live in Colorado or high altitude areas, consider anything but a Ford 6.7L diesel. Mine has problems with the DPF clogging when towing anything above 3,000 lbs. It won't passively regenerate the DPF at 70mph and active DPF regenerations are incomplete causing short intervals between the active regens. Other folks are having the same issue with the 2nd gen 6.7L emissions system.

I can't believe that wouldn't be true of all diesels at altitude. It's not like they put 20% overhead in the tuning for altitude. They def didn't on these liberties and I cannot seeing them leave that much on the table in a competitive truck market like the power stroke where every ft-lb counts. You get to altitude and you've gotta dial back the boost so it's gonna burn richer and clog up the dpf.

AFAIK, boosted engines don't need any adjustment for altitude because all they need to do is suck harder to build the same level of oxygen in the chamber as a lower spin would develop at sea level.

Problem is that it takes noticeably longer for that boost to occur and during that time the engine is not getting enough air and is pushing out more soot. The soot loading that occurs in stop/go city driving while towing a 5th wheel is disgusting. My 07 WK CRD has a DPF and in 100k miles it has never given us a problem. My 05 F350 is up to 9k miles and 6k of that was towing this summer and I hate this rig. I lost a day of vacation because the DPF got so clogged that the only way to clean it was to disconnect my camper and drive it for an hour. It would not regn/clean the DPF when towing up Woodland Park from Colorado Springs. When towing, it doesn't do passive regeneration despite exhaust temps being 700 to 800 deg F unless I'm driving 64 and slower.

Plan is to save up $2k and delete all of the emissions. No more DPF issues, no more DEF fluid worries, no more SCR, no more EGR, no more hot exhaust temps due to back pressure and burning 2.5 gallons of fuel to do a DPF regeneration every 97 to 230 miles. Last regen cycle only lasted 123 miles which is unacceptable. Best to date was 230 and that was not towing anything on a work commute to/from Denver.

Yeah, but you can only spin a turbo so fast. If the turbos already being worked at or near the limits of the what the engineers allow then they have to reduce boost as altitude increases. Turbo's dont care about the boost itself, they care about the pressure ratio from the inlet to the outlet of the compressor. Say a turbo can only make a 3:1 pressure ratio without overspinning, if you are at sea level then a 3:1 pressure ratio nets you ~29psi of boost. If you drive up to 10000' where the air pressure is 70% of sealevel, then your 3:1 pressure ratio is now only producing 16psi of boost but the turbo is spinning just as fast. Intake pressure is reduced 30%.

The OEM's can either leave a lot of overhead at sea level to keep the performance the same at altitude, or get as much power as possible at sea level and dial it back at altitude. Either way the high altitude performance is the same. My guess is that Ford(and RAM/GM) is doing the later in order to claim the the huge power numbers they do with their diesels but, in an attempt to maintain power, they try to keep the fueling the same while the turbo pressure is reduced. The negative side effect is that the AFR's are richer which increases soot loading in the DPF.

I am almost positive this the reverse technique of how GDE gets longer regen intervals on the EcoDiesel's. Eliminate the EGR, run MORE boost, and increase your AFR's so that you get a cleaner burn and less soot clogging the DPF.

Ultimately, it wouldnt matter if modern diesels didnt have DPF. Our jeeps will cut boost and dump a little more soot out the tail pipe and no one is the wiser, but the new motors with the filters have to do something with the extra soot since its not just flowing out the tail pipe anymore.

I keep saying it, but GTDI motors are where its at now. Diesel's are losing all the advantages they had. Sure you can delete all the emissions stuff but can you get away with it at this point? I've talked to a few people here in Utah that were fined for DPF deletes on their Cummins and Utah doesnt even have emissions testing!

How in the heck did they know they had DPF delete if they have no required inspections unless the owners were way overfueling and dumping a bunch of black smoke which certainly draws a lot of unwanted attention (stupid)?

This is a good article on DPF delete and the EPA!
Prod a bear(EPA) with a stick long enough and it’ll come after the antagonizer with a vengeance!!!

After reading this article, doubt very seriously that I would ever purchase one of the newer diesel trucks with all that stupid crap on them that now you cannot even remove!!! EPA forcing owners to drink the Koolaid!!!

Good lord, 2.5 gallons of fuel pissed out the tail each time is supposed to be "cleaner" than just not wasting the fuel in the first place??? Who in the actual F thought that up at the EPA and managed to convince others of it?

That is like announcing that they are going to force everyone to only bathe and drink DRY water, because normal water is too wet, but if you use three times as much, then it is suddenly dry water!
