Get rid of electronic throttle
Reckon you could fab up a couple adapters so we could shoehorn in the engine under the hood?

I can't speak directly from experience in fighter aircraft, but here's my pilot perspective: The large engines in heavy aircraft (i.e., cargo, tanker, etc.) can take quite a while to spool up from ground idle to max thrust--about 8-12 seconds--regardless of the type of throttle system used. The C-17 (my current aircraft) uses fly-by-wire technology for the throttles, but I've also flown other aircraft that use cables from the throttles to the engine to control thrust demand directly. Both setups have throttle lag. This phenomenon likely has more to do with the large rotating mass of the engine than the factory "tuning."
The last time I flew a "fighter-like" aircraft was back in pilot training--the T-38. That was a long time ago but, IIRC, it also had a bit of lag when going from idle to maximum thrust (afterburner), although not as much as the heavies I fly now (smaller engine = less rotating mass to accelerate). However, I have no complaints--the 160,000+ pounds of thrust I have now is adequate!
Back on topic: I experienced the throttle lag when I first bought my truck, but it was only apparent when using 80%+ throttle. A reflash from the dealer helped. I also got an Edge--much improved throttle response over stock, even after I got the reflash.

If not, why don't you buy yourself a tuner? I understand you don't think you should have to but if it is really annoying you that bad. .

It had to introduced somewhere why not the flagship F150? If your so unhappy with it then why did you buy it in the first place? Get used to it the drive by wire is going to make it's way through Ford's entire lineup eventually.

My truck never had throttle lag on my 2004; in fact it may come on a little too quickly.
I've used several brand tuners on it and all were well worth the price, but I noticed little difference in throttle lag, just a big improvement in performance and shifting.
If you have throttle lag get it re-flashed or get them to fix the throttle body, which is a common problem.
I have had throttle lag on lots of other vehicles, all of which had throttle cables.
Heck, Saturn’s are so prone to throttle lag from cable drag that lubing and repositioning the cable is a standard maintenance thing.
I prefer drive by wire after driving my truck for two years. Pedal is easier to work and much more consistent. And there is no cable to stretch.
And as to ‘there should be no reason to buy aftermarket to fix problems’ that is a common but impractical concept.
If you want a production vehicle to sell for a reasonable amount it will NEVER be ‘all things to all people’.
One guy’s high performance is another man’s slug.
A truck that was made to your personal specifications would cost a heck of a lot more and the next buyer would hate it. All cars are compromises and these trucks are mass produced wide usage spectrum vehicles.
I think they do a heck of a job making them versatile, reliable and stylish. And at a pretty low price.
I’ve had new cars that cost three times as much as my truck and had a LOT more complaints.

I had throttle lag until I tuned it. The biggest improvement was that now I go open loop instantly at WOT (70% or more) where as with the stock tune it would have a huge delay up-shifting and down-shifting (3 maybe 4 sec) before it would go open loop at WOT. My torque management is set up differently now too
