Description
The STILLEN TruControl Inline Power Module for the 2022+ Toyota Tundra 3.4L Twin-Turbo V6 is a plug-and-play performance upgrade engineered to unlock substantial horsepower and torque gains without modifying the factory ECU. Designed specifically for the latest-generation Tundra, this inline tuning module increases boost pressure and optimizes engine parameters to deliver stronger performance across the entire power band.
The TruControl by STILLEN installs directly into the factory wiring harness with no cutting, splicing, or soldering required. Installation takes approximately 15 minutes, making it one of the fastest and most accessible performance upgrades available for the Tundra. Once installed, drivers experience significantly improved throttle response, stronger midrange power, and enhanced towing and acceleration performance.
Dyno testing shows nearly +100 flywheel horsepower potential with gains of up to +80 ft-lbs of torque at the wheels, making this one of the most effective bolt-on upgrades available for the 3.4L Twin-Turbo V6 platform. At 3,000 RPM, wheel output increased from 176 HP and 309 TQ to 219 HP and 389 TQ, representing a gain of 43 wheel horsepower and 80 wheel torque. Peak rear-wheel output reached 352 HP at 5,100 RPM, an additional 45 RWHP over baseline.
The TruControl system features Bluetooth connectivity and a free smartphone app, allowing users to select, adjust, and reset calibrations on demand. The module comes preloaded with up to seven selectable tuning maps, including Race, Sport, and Eco modes, allowing performance to be tailored to driving style and conditions.
Custom over-the-air tuning files are available when paired with supporting STILLEN performance upgrades such as exhaust or intake components. The module is fully removable, allowing the vehicle to be returned to stock before dealership visits to help maintain factory warranty coverage.
A 14-day satisfaction guarantee allows customers to test the TruControl by STILLEN risk-free in their own vehicle.
