Real dyno results
Here's a real Dynojet pull on the 5.7L V8 Tundra — stock versus the naturally-aspirated OTT calibration. Peak horsepower barely moves (~301 → ~307 whp), and that's the point: the OTT tune is drivability-first. It adds about 27 lb-ft of peak torque (~335 → ~362 lb-ft) and brings it on roughly 860 rpm earlier, filling the midrange where the truck actually drives, tows, and crawls.
Professional ECU tune for a 2021 Tundra (5.7L V8)
A 2021 Tundra with the 5.7L V8 is fully supported. Tuned Yota installs the OTT calibration in person, in about 15–20 minutes, at events across MN, IA, WI, ND, SD and NE, from $500. It is a drivability calibration, not a horsepower chase: on our Dynojet pull the 5.7L gained about 27 lb-ft of peak torque (~335 to ~362 lb-ft), arriving roughly 860 rpm sooner, with factory emissions intact. The 2021 is the last model year of this generation; the 2022+ 3.4L twin-turbo is on a wait list.
Supercharger & Turbo Support
Supported Tundra platforms can run a supercharger or factory-turbo performance calibration for the biggest gains, Tuned Yota is an authorized Magnuson retailer, installer, servicer, and calibrator, and also supports Harrop and ProCharger. Want the big number? On a Magnuson Stage 1, supported 5.7L V8 Tundras put down ~450 whp — see the dyno on our Magnuson supercharger guide.

An OTT Tune is a custom Toyota Tundra calibration focused on real-world drivability, throttle response, shift behavior, reduced gear hunting, larger-tire drivability, towing confidence, and overland-ready response, and more usable power where supported. Every tune is installed by a certified Tuned Yota installer.
On supported Tundra platforms, yes, calibration can improve shift behavior and reduce gear hunting, which is common after larger tires, added weight, towing, or hilly driving.
Yes. Lifts, armor, racks, and recovery gear make your Tundra feel heavier and lazier; the calibration is designed to restore drivability and response, where supported.
