All kinds of wrong. The heads on these trucks are capable of stupid numbers in stock form. The first bottleneck, since the DPF is gone to achieve those numbers, is the factory intake followed by the turbo.

Exactly my point. Removing the DPF IS a major mod. You would be amazed at how much air the intakes on these trucks will flow.

I don't see removing the DPF as a major mod. Reason being is that a lot of people do it. Major mods start with turbo and pump upgrades IMO. Very few travel down that road when compared to the number of only a tune and delete.
The factory intakes don't flow enough air to keep big tunes happy. It's been proven since the 6.4 days. The physical hardware on the trucks (factory Gt37 charger, HPFP, injectors, etc) are clamped down from full potential by the intake. It's why they changed the design in 2017 of the stock intake and they only bumped up torque from 860 to 925.

I actually think the 2016 and older PSD's were a better design. On the 2017 the battery and filter swapped locations. Meaning the air coming from the outside of the truck has to travel into the engine bay, under the battery, and finally through the intake.
That's why I like S&B's kit because it relocates the battery so that the "enclosed filter" is right where the air is entering the engine bay.
AFE for an extra fee (which I believe their products are overpriced to begin with) will give you a band aid of a part so that the air goes over the battery and into the filter.

When a fuel system gets a bit of water into it and it ****s itself for a cost of 10-12k for replacement. We can do better than that. You could add a better fuel filtration system. Instead of 10 Microns and the main and 4 microns at the second filter. Make a system that runs twin 2 micron filters at the main first. Then a third 2nd micron filter at the injectors. This could help.
I'm not saying that Ford does not make a great product, I feel the do, but there are always ways to improve on anything. This is why we have the after market systems that look at this possible issues and corrects / fixes them when available.
I believe in insurance when ever possible. If it costs me 800-1000 dollars for additional filtration, then I will add the product for a sense of ease.

Factory intake is "cold air"
dont waste your money on aftermarket intakes , if your keeping stock fuel,
and remember better flow = less filtering for same surface area filter. So if you crank her up to 600 rwhp, there are some gains to be had, but you will suck more dirt.
