If I read that right, you want to intermittently restrict airflow through the intake side? That will hurt mileage, not help it. Anything that restricts airflow will hurt mileage. One of the ways the DOD engines increase mileage is, in 4cyl mode, the throttle body opens up almost half again more, which makes it easier for the engine to draw air in. If anything, you want to open up the air intake so that there's no restrictions at all.
If you had the research money there is some value to tuning the air intake tract to use the opposite of exhaust scavenging to help fill the cylinders, but a better (budget-wise) way would be to just build a ram air setup to help use the truck's momentum through the air to push air into the engine. If the engine isn't having to suck its air in, the energy that would have been used to suck air can go to the rear wheels instead.
Yes, exactly what I'd be doing. The design of the air box and intake tract are so the engine performs well over the 1000-6000 (whatever redline is) rpms. I only ever intend to use it in the 1000-3000 rpm range and believe I can successfully choke down the box under low load conditions to gain some low end torque. The knowledge learned with the air box mods on the Ram helped me a lot to understand how the flow affects performance (on a diesel anyways). Next will be this engine... now that the JTCM is in there I can see it definitely needs help in the 1400~1600 rpm range. It is not bad, (and I am going to leave the JTCM in there for now) but it can definitely benefit.
The drive into work this AM showed me where I need to work on the torque, after this tank (which is probably learning anyways), I will play with the air box flow and see what I can learn. Some recent research pointed me in the direction of airflow velocity improved torque (in general), did not get to read the entire article/white paper as it was 2a at the time I found it...
edit: forgot to add that I have a couple of intake tube ideas/setups I may try... the idea comes from the Rams setup. It would have been nice if the Airaid intake tube fit, an email to them yielded nothing so I will have to buy couplers to try it out.

Sigh... dak sidelined for brake failure, left side caliper has moved and is now grinding down on the rotor. I suspect the drilled & tapped slide pin hole has failed. I have the heli-coil kit in hand and enough inserts for all 4 holes. May go that route as a short term fix.
Alright, just filled up and calculated 14 mpg with normal work/heavy traffic on the old MAP. This will be the first tank with new sensor.
This tank will be a bust. Been stuck in super heavy traffic 2 out of 3 evenings so far, driving from work to home. Took me like 20 min to go two miles last night. It's never good when you see choppers overhead.
This is the original starter on this truck and it's been stellar. I'm sure it can handle the addition of start stop technology, cause I'm going to make this truck a hybrid.
Who's been looking at that new Ford Maverick?

I have not... I have been shying away from anything newer and more complicated. The Ram & Dak are super simple to work on which makes it easier to keep on the road, I like that.
On your tank, how does the odo vs fuel gauge look? I can generally tell if a tank is going to suck or not by how much fuel is used by 3/4 tank & half tank marks on the gauge. By then enough miles have piled up to get an idea of how it is going.

The Maverick is a hybrid pickup that supposedly gets 42 mpg city and 33 highway... better than a compact...and it's affordable. Probably reliable... the Ranger is pretty good. Oh, the mileage is sucking for this tank, alright.

Personally i don't believe in a hybrid, or fully electrical at this time.
On the hybrids you have different variants, ones that drive fully electrical until battery power is to low and changes over to drive further on gas, or the ones running on gas with a little support of electric power.
With the 2nd version of hybrid you drive on gas all the time, only advantage is you don't have to charge it and you're mileage will improve a bit, it's cheap compared to fully electric, but will still cost you a lot of gas.
With the 1st hybrid you can start off electric, but you have a radius wich is to little, so you end up driving on gas when you run out of battery power, you'll have to charge it whenever you reach you're destination.
In the wintertime, like over here it's just below freezing right now, spoke to some one who has the BMW i1, and is complaining his radius dropped with 1/3 with this temperatures.
I've made some calculations and there's still no benefit in total cost, even with the high gas prices over here,but this can change over very soon, depends on prices and restrictions of government, and what they want to get us out of gas powered cars, over here there will be no more gas powered cars delivered in 2024.
I have 3 options at this point, most of us will, continue driving our cars the way they are ( at this time cost me about the same as fully electric ), but in my opinion i have all the benefits of a wide range, fill it up in 2 minutes and drive where ever the road leads me.
2nd options, convert mine to fully electric, take out the V8 and put either 1 or 2 Tesla electric engines in, this isn't cost effective at this time, but probably will be in the future.
3rd option, buy a fully electric pick up and keep the Dakota for back-up...... will cost me very much..... might be the option in the future.
I don't have the room for a full size, and i don't need it, so if i had the money right now i choose the Alfha Wolf.
The Rivian R1T is available too, and when you didn't pre-order one, you have to be patience......same as the Ford...
I don't know how prices compare in the U.S.A., but it will varies in a lot of different ways, when you look at cost to drive versus a gas/diesel truck.
I think every situation is different, and everyone has a different opinion on electric versus gas driven vehicles, only thing i see going on is we are forced to go electric in the future, despite the discussion if it's better or not for the environment, and i'm not going to start a discussion on this topic.
Over here in Europe we've got the news bulletins that the Alpha Wolf was going in production 2023....but reading you're link.... this is likely not going anywhere....
Thanks for the reply, even though i like to drive my Dakota at least for a couple of years, and likely to convert it in electric when time comes....
