I want what most want. More power. I don’t really care about the high end but I would love to eventually see a 20% increase over stock Trq. I travel for work with my wife and son. We are full time in a camper (upgrading to 5th wheel later). Depending on our total load out I’d tather not have to worry about driving 15-20mph up a 9-12% grade. Any increase in HP is of course fine with what comes in trq gains. I plan on a programmer/tuner of course. Exhaust, CAI (if it is worth the money), possibly bigger turbos down the road, who knows... the options are essentially limitless
My stock truck will pull a 15K trailer up the steepest interstate climbs in the US at, or above, the posted speed limits pretty much effortlessly. 9-12% grades are rare and those you find are typically 2nd and 3rd tier highways that I wouldn't want to tow "at speed" with that kind of load, regardless of the truck's ability to do it.

Don't care what you have for a CAI, the PCM will control the fuel air ratio. That's not going to change without a tune.

"We are full time in a camper " If by camper, you mean a travel trailer? You have a '17 6.7? I full-time pulling a 20500lb fifth wheel, now passing 44k miles towing. If you have a '17 6.7 or later and can't pull a camper/travel trailer up a steep grade fast enough, then something is wrong with your truck......as mentioned, those 9-12%, even 14-15, are rare around the US and to try to tune for just that pull seems odd. But, if that is what you want/need to do, you are going to have to do some serious emissions deletes/tune app to get there--all for the rare time you encounter a steep grade???
And if you look at my sig closely, you can see what a tune can do to a 6.4L. Granted, not the 6.7L by any means, but the regen systems on the Fords put a lot of stress on the rear pistons and sometimes.....

If a company can't go to the trouble to proof read their advertising copy, I have very little faith in their ability to accurately test their product.
Yes, I am old school. Nothing wrong with that, in spite of your poor attempt at inferring that is a bad thing. This old school guy once installed a Chevy 283 in an Opel Kadett.
Every drive train I have ever modified for performance went on a dyno with each incremental (and documented) change. That's doing it old school. Reading the hype on a box and reporting that as a real world gain is foolish.

And this is why I don’t post that much on this group cause of the misinformation from the people thinking “if it’s better Ford would had done it” mentality. To many old timers in this group thinking stock is the only way and has to be the best way cause “ford did it that way”. I’m sure you think swapping the stock innercooler for a aftermarket one and the stock CAC plastic pipe for a aftermarket one that doesn’t blow is wasted money.
Yeah, I see why it’s attractive...

It’s your truck, and you should equip it any way you want and have fun.
But, when someone is asking a question about an aftermarket part that has been determined to be a total waste of money, expect to have the facts presented.
Not only are they they totally worthless, but Diesel engine health depends on tight tolerances. Those tight tolerances are maintained my clean oil and clean air. Aftermarket CAIs do not flow more clean air than stock...more flow means the media allows more air to pass by the filtration process. Even if they allow more air, the engine’s programming can’t process more available air into power.
Waste of money and hazardous to your engine to boot.

Of course, I get that.

I'd be insulted if your opinion had one shred of value.
So I'm not.
