I just ordered the Sxth Element TRC throttle response controller. At $179 it seemed like a good alternative to the $299 Pedal Commander. I should receive it in about 6 days and get it installed fairly quickly after.

I installed the pedal commander, say Goodbye to what little fuel mileage you had.
But Hey, you can burn the hell off the tires if that's what you want to do.. I
unplugged mine.
I'm gonna look for a more solid tune

With the option to actually tune fuel, boost, variable cams, and transmission, I don't see why anyone would get a pedal commander. All it does is change the way the pedal and throttle plate correlate. Good call on waiting for a real tune!

Sport mode does not accomplish what I am looking to get out of it.
Unless I am actually shifting it, hypermiling it. I'm unable to get more than 14 miles to the gallon. In whatever mode, the truck is in.
I know a lot of it is all the weight that I have added, but most of it is, they lied.

Try out the throttle controller and see how it works. Eventually you'll probably want a real tune so that hp and tq are increased as well.
Ah, you're trying to reduce power.
Have you tried putting the truck in Eco Mode? That will do more than any pedal controller - pedal response, shift points, and boost curves. All that any pedal controller can do is electronically replicate moving the pedal more/less, or faster/slower (which can also be done with your foot).
My experience is anecdotal with my single truck:
(Stock aside from LT275/70R17 C-rated tires)
In Normal Mode, over the winter, driving mostly in hilly/mountainous terrain with 50% of my miles on snowboard trips, idling the truck, and driving 5-10 above speed limits (65mph max speed limit around here), I averaged around 17ish MPG.
In good weather, on flat ground, in Eco Mode, and driving like a grandma, I can easily hit the rated fuel economy specs. And that's what they are based on. Toyota didn't lie in my opinion. The truck, in stock form and running correctly, is capable of hitting the rated numbers under the conditions in which they were calculated.
This truck is a turbocharged 4 cylinder that's tuned to 116hp/L. That's somewhat "hot" tuning, which requires more fuel per liter to do more work compared to a larger engine that has more conservative tuning. That causes any additional load in the form of weight, aerodynamic drag, larger/heavier tires, etc, to use more proportionally more increased fuel than the larger engine would.
This is the biggest difference between a turbo-4 and a naturally aspirated V6.
For example, adding larger tires or 1000lb of stuff to a 4th Gen Taco may drop the fuel economy from 18/23 to something like 13/18mpg.
Compare that to a 2nd Gen Taco with a 4.0L NA V6, rated at 16/20 mpg. The same added load would reduce the fuel economy less, but still down to maybe 14/18 mpg.
The only good solution would be to regear the differentials with lower gears to offset some of the load and potentially larger tires. Most people don't do this because it's expensive, but it's the correct thing to do for larger tires or heavier loads.
