Just cleared 1k miles today. 2019 TRDP is averaging 16.4 mpg in mixed driving at 5-6k ft elevation. Added a Pedal Commander two weeks ago and it has improved 0.1mpg. I'm pretty sure this is as good as it gets for me.
Well I was getting 18mpg then did a tune up and now get 15mpg if I'm lucky?? New spark plugs, PCV valve, air filter, cleaned the MAF, cleaned the throttle body (off the truck and replaced the gaskets), new transmission filter and fluid swap, new diff, transfer, brake, power steering fluid, serpetine belt. No stuck calipers or anything. Running tires at 34 psi. Think I might try replacing the o2 sensors.
Was getting 17mpg, mixed city/highway. After installing TRD CAI with AEM dry filter and TRD catback exhaust, now getting 19mpg.
2017 SR5 Premium
Wow...I may look into getting a CAI. Did you install both together or at separate times?
Drove about 900 miles from Texas to Arizona with a 5th gen T4R with about 2500 miles on the odo.
Mods done - stock size BFG kO2s, steel low pro bumper, and steel front skid plate with about 100 lbs in the trunk.
Overall MPG over this distance was 19.1 based on the computer. I departed very early in the morning and she was at 17 ish for a long time when temperatures were low (20-25 F) but mileage got better as the day went by. Speeds were consistently in the 70-80 mph range through this distance. Will be driving to LA today and will drive back to Texas after the holidays but with a front runner slimline installed so will do a mileage comparison over the same route and same distance with a roof rack installed..
You can use a tool on edmunds.com to show the true cost of ownership of a car over 5 years and see if it makes sense for your situation. For example when I tried it, buying and driving a 2019 4R 15K miles/yr for 5 years results in (depending on the model and your location) a total of about $53,800. A Prius compared at about $36,000.
What’s interesting is the cost of fuel for the 4R in CA is $16,400 vs Prius at $6,400.

Im just passing 1000 miles on my '19 Pro.
Lots of stop and go interstate traffic (I-270 for those in the DMV). Its lucky for me to cruise at any speed, and anytime I finally get to 5th gear I have to break down to near stopping. In other words, this car was not made for my commute. Im fortunate work pays my gas.
Im at 17.4 as of today, but its been bouncing between 17.3 and 17.5 for a week now.
Im expecting it to raise a bit further, but not much. max out around ~17.7 is my estimate. Probably low 18s when my commute is no longer on I-270 in the future.
