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?

Not sure about what the future holds but I am not looking forward to owning a silent tow truck! Down with Tesla!!

I dont think the arguement for improved fuel mileage compared to the cost of a delete by a diesel shop makes any sense. The gains I see most people claim are about +2 mpg. Runs those a very long time to recoup that investment. You are talking about driving at least 200,000 to 300,000 miles before breaking even!! Especially considering that I bought diesel at $1.78 near Houston last week!! Really not a valid arguement IMO for a delete whatsoever considering JUST this factor. And remember, this turbos will almost certainly fail sooner with a delete due to fairly significant increases in heat.

Good discussion. Like I said, gonna wait for more 2017+ owners to be test subjects. It does seem to me that a great majority of people who support a delete, are not looking into the Engineering improvements made on the latest generations of 6.7s. My biggest concern is actually getting WATER in the injection system NOT my emissions. So I am adding a secondary Racor fuel filter / water separator. This is a $100 mod that makes total sense to me!!

At typical fuel prices (let’s just say $2.89) it’d take bout 125,000 miles
to recoup $2,236

Let’s just say there are no Benefits as to longevity; deleted truck will last as long as one not deleted (which is hard for me to believe). I pretty sure an egr and dpf will eventually fail maybe later than sooner but it will. So at that point it will be cheaper to deleted than to replace emissions components. So why not go ahead and delete sooner the payback should cover the cost long before the egr and dpf would fail if left on. Or leave it on get 2 mpg less and less hp and if you keep the truck long enough pay more to replace emissions equipment than you would to delete. Do whatever you want. To each his own.

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’ve often wondered the same about emissions on tuning; does that mean it’ll clog up faster??

DEF at Walmart is about $13 for 2.5 gallons. So after I drive 125,000 miles, I will have (cattle) pissed away about $3250. Something to through into the equation.
