Should you delete 2017+ Powerstrokes???

Valid Reasons for Deleting 2017+ Powerstrokes???

Hey folks,

So I have owned the 7.3, 6.0 and now a 2017 6.7L with 37,000 miles. We all know all the benefits to a full delete on the 6.0s, 6.4s and early 6.7s.

So the poll question is, should you delete 2017+ 6.7l Powerstrokes or not? If you vote, please share your perspective and hopefully real-life experience with this motor.

Like most, after purchasing the 2017, I immediately just ASSUMED a full delete would be needed to ensure long-term reliability. However, after researching the topic and looking at all of Ford's improvements in this newest 6.7l generation I have come to the conclusion that a delete is simply unnecessary. I am not seeing reliability issues related directly to the emissions on these trucks. So deletes, especially for low mile trucks (under 100k), seem to be more "fad" than a choice supported with evidence. Appears to me, that many guys/gals are simply making assumptions on the benefits due to prior year emission related issues (certainly for pre-2015 powerstrokes).

While I am no tree hugger, I also think retaining the emissions is the responsible thing to do for our environment, especially if the performance benefits are small or unproven and not quantified. Not sure if there is enough data available from 2017+ deleted truck owners at this point. I also use my truck strictly for heavy towing (15-25k loads), not for show boating, so my perspective may be different. I do plan on having over 300,000 miles on this truck with 10+ years of ownership. So if a performance mod will significantly improve engine life and reliability I want to do it. As such, my 1st mod was a Amsoil dual bypass oil filter system.

But I wanted to get people's perspective on this? I assume this is a highly debatable topic. It would be superb to hear opinions from professional diesel mechanics with years of experience on the newer 6.7s?

A large percentage of the problems with the 6.7 are from the DPF/SCR/DEF system itself. While you will probably never recoup the cost of a delete on a 6.7, one of the biggest benefits in doing it is the better fuel mileage. The extra cost of regens and DEF add up time. As far as most performance gains go, there's no real reason to delete just for that, especially just for a tow pig. The tuners are getting pretty good numbers with emissions in-place tunes these days. Now if you're really planning on jacking up the power numbers with big turbos, injectors, intake systems, etc. then you would be silly not to delete to start with.

As mentioned above, with good tuning, today's diesels burn so clean that there's really no need for these systems at all, but that's what you get from an untethered EPA and a few snowflakes. It is my opinion, when it's all said and done, that the DPF/SCR/DEF systems and the baggage associated, are as big of a polluter as anything.
Thats what I’m thinking. Some advertise gains of 150 hp with em on tuning.
I have no data to back it up, but it seems reasonable to assume if you use the extra HP in a tune, you are going to create more soot and clog the DPF up sooner. However, You are not going to be in the throttle all of the time, so it's probably not that much quicker, depending on how crazy you are. Also, most tunes do not really make a lot of changes from light to mid throttle positions (ie. normal driving), they ramp up the tuning after mid throttle. So technically, a 200hp tune isn't running a lot different from stock on normal driving, but if you mash it, you'll feel it.

That makes sense. I didn’t think about it that way. I can tell my throttle is a lot snappier tuned and the truck does seem to get rolling quicker with light acceleration. The emissions compliant tuning may not be as hot though.
I didn't say they did nothing at light to medium throttle. It's just not all that much. Most any tune will help with throttle response, but the bug gains come on after half throttle.
