Toyota Sequoia Accessport Tuning
Introducing Accessport Tuning for the 2023 + Toyota Sequoia
Toyota’s twin-turbo 3.4L V6 hybrid powertrain already brings serious capability to the road, and now you can unlock what the factory left on the table. We are excited to announce Accessport tuning for the 2023+ Toyota Sequoia. Combining both engine (ECU) and 10-speed transmission (TCM) calibration into a single handheld device and flash, this release delivers dyno-proven horsepower and torque gains alongside sharper, more responsive shifting. Available right out of the box with pre-loaded Off-The-Shelf (OTS) maps for 91 and 93 octane—plus full custom tuning support via Accesstuner Pro—it’s the ultimate plug-and-play upgrade for daily driving and heavy towing alike. Best of all, the entire package is 50-state legal.

Gain access to real-time data, comprehensive logging, and one-touch reflashing capabilities, just like the rest of the Accessport lineup.
Proven COBB Performance
Built on over 25 years of ECU calibration experience. While Toyota’s tuning infrastructure is more advanced, this demonstrates our ability to deliver reliable, performance-driven calibrations.
Off The Shelf Maps & Power Gains
The Sequoia uses one computer to control bot the Engine and Transmission which gives us the ability to offer multiple variants of our Off The Shelf Maps. All Stage 1 maps are intended to be used on an otherwise stock truck.
