Well, just ask an RV owner with a Ford V-10 how they like the mileage. Most are lucky to see 8, with a toad, 6 and those are generous estimates. Your 1400HP gas engine will get truly horrific mileage. Now install a powertrain and cooling system in it that will handle that power and you’ll lose a boat load of your towing capacity and reliability. Diesels are simply more fuel efficient for a couple of significant reasons. Economic sense is for each to decide, but in my mind a diesel is a must if towing anything north of 8,000 lbs and the only realistic option is a factory diesel with the millions of R&D that goes with it and a warranty and dont forget the resale value that will be there at the end of road.

In my opinion, I believe with the mandatory def system and the ridiculous MPG requirements put in place buy the California air quality management control, yes California set's the smog standard for all automobiles in America (how stupid is that). These people are environmentalist, not engineers, they have brought down the reliability and the economy of the diesel engine. My old slightly modified 7.3 has more horsepower and torque, no smog and burns alot less fuel then my 2016 6.7 Ford.

And CA only sets the standards, engineers then design it all and make it happen - there is a reason that despite all these terrible air quality standards trying to keep our air breathable, the trucks still perform and are reliable.
I frankly cannot understand buying an expensive truck, to then turn around and dump a bunch of cash into it both voiding the warranty, and introducing a ton of failure risk into the engine. But to each their own I guess....

I’ve installed quite a few superchargers over the years both for customers and myself. I haven’t got my hands on a gas 7.3 yet but If I were you, I’d go with the Whipple SC over procharger. I’ve owned both and the reliability and drivability of the Whipple was much better than the procharger. You have to wind the procharger up to get boost and get in the power band but boost is right off idle with the Whipple. You have potential for more issues than stock with both systems but I’m guessing that 7.3 would be an animal with that Whipple. Unloaded mpg would probably be the same, if not better by a few mpg. Depending on the terrain and how heavy your right foot is, towing mpg would possibly be the same but probably a little worse however, you would have a big grin on your face going up hills and passing slower traffic.
I’ve been tossing around the idea of supercharging my tundra but I don’t want to accidentally make it unreliable. I’ve been there, done that.2020 Grand Design Imagine 2400BH

Toyota use to have a factory warrantied supercharger for the Tundra that many put on the 5.7. Was a dealer installed option if memory is correct. Not sure if they still do for the newest models but the 5.7 has not changed at all so I would expect that you can still get these.

Toyota discontinued the TRD SC for the 5.7 (as well as the Tacoma/FJ 4.0) but you can still get it through Magnuson, which built them for the TRD Toyota brand, they just say Magnuson instead of TRD. They’re a good, dependable blower and kit with consistent, reliable results. We now have Harrop and Whipple offering kits for the Toyota 5.7 with bigger displacement blowers, bigger intercoolers, injectors and fuel pumps that will add more power with the right tuning. If my lottery numbers line up tonight or tomorrow, I’d probably go with the Harrop, with a strong look at the Whipple kit. I’ve driven a few SC’d Tundras and they are a completely different animal than the NA version.
