The reason for deleting a 2017+ Powerstroke are the same as they are for any 08+ diesel truck, better reliability, more fuel efficient, less maintinace and potential issues down the road, and more power.
Keep in mind most big companies like that are under close watch by the EPA, it would benefit them more to feed you propaganda than to tell the truth, or they are just trying to sell their product.Not arguing against the "traditional" justifications for a delete. However, in reality there is no imperial evidence that shows a WELL MAINTAINED (not hot rodded) truck in stock form = less engine life than a deleted motor. And BTW, I was always a fan of deletes, especially with older versions where the emissions systems where rather new (6.0 and 6.4 especially along with Duramaxs and Cummins, etc).
However, I would like to bring up some articles that argue or warn against it so others can look at both sides and make an informed decision. Also, the EPA is heavily cracking down on aftermarket tuners in just the last 2 years. Scares me a bit. Plus you do take a hit on aftermarket value if your truck is deleted (I dont plan on selling mine...driving it into the ground).
Some opposing articles that warns against it:

Diesel Tech Questions: Emissions Deleting and Checking Codes

Overall, I completely agree with reasons why to delete. I am just not 100% anymore they outweigh the con's. And the EPA risk is becoming much higher as they crack down on aftermarket companies.
My plan is to sit and watch at least for another 30k miles or so. Let my warranty period end and see how these newer trucks are doing in stock form with 200k+ miles.
