Just curious, but how's the mileage around town and I'm the highway? What's your highway cruiser speed like? This is an intriguing recommendation.

I get 10 to 12 around town with mild at 35s.
14 or 15 hwy.
Cruises at any speed limit fine. No different from stock really as far as noise from engine.
Passing lanes are really fun!
Best analogy I have is go-kart like, particularly in etc mode.
I am sure that @VooDoo2 who is an Aussie could chime in with some valuable insight since he has built at least one highly modded supercharged 200. Here is his first build thread;
forum.ih8mud.com
and the new build he is starting;

IMHO this guy is at the forefront of these builds his first build was epic, and the second one may well be even better. It would be nice to hear his two cents on this thread.

VooDoo2 / ToyoTrek NEW Build... Dual cab 200 Tourer
So New build, not that i have finished with the last one but new business means another car is needed. This one will be a dual cab 200 conversion, Jmacx Chassis, front and rear winches, Fabricated diff housings with 4.3 gearing, lockers etc. Gulf-Lander Touring canopy with hydraulic struts on...

Had superchagers on a couple Tundras one for fun and my last Tundra was 2016 was plenty of power , had to run 92 octane was a thirsty beast .
I end up swapping out the Tundra for a Diesel truck , cost of fuel and the ability to haul twice as much ... Would have loved to have a Toyota Diesel but they don’t have a small Hino diesel in the USA so settled for Duramax has a Denso injection system is close as I could get .
I personal don’t see a need for a SC on my 200 , I think the 200 has more than enough power from the factory ,
Also did the Big Brake TRD conversion on the Tundras made a big difference , after all that new GMC diesel save me a lot of work , could have kept throwing money at the Tundra but would have been a waste .
Just my 2 cents on a SC

My 200 is a twin turbo Stroker DIESEL not a supercharged petrol but ive been there too... HSV GTO

Nobody needs a supercharger, but once you drive a supercharged 5.7, everything else feels really slow.
How heavy is your foot?
When I first got the truck back and was keeping it under 55 and being extremely light on the throttle during the gear break-in I got about 14 MPG in pure city and I actually hit 20 MPG on the highway (meter read 19.1 MPG but multiply by 1.05 to account for 34" tire size). So if you're willing to NOT drive it like you stole it, you can get 20 MPG even on 34" A/T tires if you add a winch bumper, lift, roof rack, etc. That said I've NEVER driven my truck like that before so I have NFC what a stock truck will get if you actually drove 50-55mph.
Driving 15 minutes up the highway last week at 75mph on a windy day I was getting about 15mpg. If I can keep it there on long trips I'll be happy, since under the same circumstances I was getting 12-13 before.
This tank I've got maybe 11-12 mpg but I'm very heavy on the gas from the lights and it's largely city driving but with ~15 miles of highway and ~20 miles of towing mixed in so it's a meaningless metric. Just broke in my gears a couple weeks ago and I've only put maybe 100 miles on it since, so my current mileage has too much of a margin of error atm. I should have more useful info later this summer.
In short I wouldn't re-gear for the MPG savings, though if you're on stock gears with bad aero and big tires it probably will help a bit. If you have a heavy rig with bad aero and big tires and you tow a heavy trailer however it's a huge improvement.
I'm early in my build, but this may change things drastically. Frankly, I'm not going to go the SC route for reliability, but I'm running 33" AT and am getting 12-13 mpg around town driving pretty wimpy since we have a baby. Seeing that this will be a road trip machine with terrible aero and will eventually be fully built, this input will certainly change the timing on when I'm willing to re-gear. The ability to drive my car more "fun" coupled with better mileage makes it a no brainer. I was just worried about possibly being able to cruise up to 90 on super rural stretches that have 80 mph limits. I wasn't sure how much of the top end is lost. I'm not looking for triple digit performance.
Honestly tires make the most difference in mpg in my experience. Winch bumper was second
I’m not sure your model year but on the 6 speed 4.30 is probably the ideal ratio if you do regear for 33s or 34s. 3.90 on the 8 speed. Shorter (higher numerical) gear ratios are more fun around town and better on trails, but you’ll get better mpg on the highway by not over-gearing.
For the later 2016+ with 8-speeds, gearing will not give them quite the boost those of us with 6-speeds see. 8-speed stock 1st gear overall gearing is already in the ballpark of 6-speeds with 4.88s, 15.857 to 16.265 respectively. Versus stock 6-speed first gear gearing at 13.029. The 8-speed has always had plenty of gear, even for increased tire sizes.
Torque and HP are two very different things in my mind. Torque can be multiplied with gears. HP cannot. Torque gets you off the line, everywhere else is HP. Freeway, uphill, and passing power is HP. So long as the transmission can downshift and get into the 5.7s powerband, it has enough gear.
It's been said that Americans drive torque, and there's much truth to that. Most impressions from gears are from low RPM engine performance. For casual driving, it'll feel great, and why people love diesels and electrics. For example assuming the 5.7L max tq is 401 lb-ft. Let's assume a 6-speed with 33s with stock gearing. A simple theoretical max motivational torque at the tire is 403*12.239 = 4,932 lb-ft. With 4.3s = 5,424 lb-ft. 4.88s = 6127 lb-ft. Yes, big differences that one can certainly feel, especially when laden.
Once at speed, because gears don't make HP, it's 401 HP level performance all day.
That's where real HP adders, like superchargers earn their worth.

Can u post a pic of under the hood?
I'm not necessarily looking for the HP gain. I have a car with a stupid power to weight ratio when I need it. That said, I have the ten speed and honestly was wondering if the gauges were digital when I upgraded to 33" AT tires, but noticed no difference on the speedometer vs GPS. Sounds like re gearing won't really help. Thanks for the knowledge guys.
285/55/20 Toyo at3 getting abt 2 mpg more
Would love a supercharger on her an see if she can spin all 4 like my 15 duramax

Looks sexy! Was there a big difference in ride quality from stock size to 285/55/20?
Yes it rides a lot better now IMO
Couldn’t we go after some used third members for some 3.90 or 4.30 gears to save a pile on this cost?
Yes there are people that try to source 4.30 rears from a tundra and fronts from a 100-series LC/LX. Or for the 8 speed getting 3.90 gears from an earlier 200. There is a whole thread on that effort. Other ratios may be harder to come by. Whether or not it saves a pile of cash is TBD of course
I had planned an XAT Racing 6.8 liter build with a stage 2 Magnuson 2650 to make a street bruiser, but hearing that tuning may be a big issue, I'm rethinking it. I know this is an old thread, has anyone in the states been able to do the Dubai tune? I'd love 1000lb.ft for the street. Make them Charger drivers doubt their purchase.
Yes, please, bring some of the Middle Eastern enthusiasm and progress for big power to North America!
I’m not aware of anyone in your area that could help but I did speak to and was impressed with the owner at Figs Engineering in Denver. And he was getting a nice new Italian AWD dyno setup. I’d reach out to both the Middle Eastern tuner and see if they will be willing to do some remote tuning with the help of someone stateside.
I want to take a ride in it eventually even if it doesn’t reach 1000lb/ft!

I've gotten in touch with YotaWerx and they are interested in tuning it, yay! By The Way, I want 1000 lb ft torque, not horsepower.
