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?

Deleted so I don’t have to deal with def Fluid. Don’t need to worry about yet another fluid level for no reason. And the tuning made the truck run so much better it’s crazy. But emissions present tunning probably does too. But if im going to toss the warranty than why would I keep it. I tow heavy all the time and def was adding up. I’d need 2.5 gal
Every 500 miles. My time is to
Valuable to keep up with that bs.
Just curious, why would you buy DEF at WM? I've never bought it other than at the pump. WAY cheaper and most definitely fresh. Are there no places around you that sell it at the pump? No truck stops?
I don’t really have an opinion on buying at the pump or not, but I’m in Vegas and get to Ca, Ut, and Az often, I’ve never seen def at the pump. Maybe I’m not looking for in the right spot.
Over $1700 for the 125,000 miles. Still something to put into the equation.
I was getting 6 mpg towing 25k loads and burning 5 gal of def every 800 miles. If I was just driving to work I’d drive a civic. 5 gal DEF per 800 miles, def would be like $8,000 dollars in 100k miles. Deleting was great investment
