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?

If my dealer wasn’t cool with deletes, I definitely would have left mine stock. In my opinion, there’s too much going on mechanically with these newer vehicles to void a warranty. Honestly though, I’ve seen a great improvement in fuel economy since deleted. With good tuning and taking it easy I’ve seen it hold 18mgp in town and 20-24mpg on the highway. On the 100hp setting, I’m getting far better mpg than my wife’s ecoboost expedition. We’ve run older diesels all my life and they’re still running everyday, I think due to good maintenance and no emissions suffocating the motor. I personally can’t stand what the emissions components are doing to these newer trucks.

I agree with the last two comments. I’ve got some family and friends who work in the service department of my local dealer and they all say most of the time, when a Powerstroke comes in for repairs it’s emissions related. The truck is a lot happier being deleted. Even on the stock power level, it feels free compared to before. The added fuel economy and not having to use def is also a bonus. I know some of the bigger tuning companies have to play by the new rules, but wouldn’t the added power from emissions compliant tuning create more problems with heat and clogging?

I'm not a Ford tech, but I work on large ag equipment and am certified on 4.5l and 15l Cummins if it matters. If it wasn't for emissions related crap, I wouldn't have much engine work
Do you happen to know if there’s any deletes for the John Deere tier 4 engines? This is something I’d like to do after the warranty expires.
I’ve often wondered the same about emissions on tuning; does that mean it’ll clog up faster??

Thats what I’m thinking. Some advertise gains of 150 hp with em on tuning.
There's a guy up here in Helena that does them. I work for JD and only know of a couple that are deleted in this area.
Cool! Glad to know there’s kits available. Now all I gotta do is convince the boss man.
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.
Guess I meant, would the added fuel delivery for quicker response create more Dpf and egr clogging?
