Description
The STILLEN TruControl Inline Power Module for the 2021–2024 Toyota Supra 2.0T is the easiest and most effective way to unlock hidden performance from the B48 turbocharged engine. Designed for street-driven performance, this inline tuning module increases boost pressure and optimizes key engine parameters without altering the factory ECU.
The TruControl module installs directly into the factory wiring harness with no cutting, splicing, or soldering required. Installation takes approximately 15 minutes using basic hand tools. Once installed, the system delivers substantial gains in both horsepower and torque across the entire RPM range, dramatically improving acceleration and throttle response.
Dyno testing shows gains of up to +60 flywheel horsepower and +107 wheel ft-lbs of torque, with peak wheel horsepower increasing from 245.5 to 297.3 and torque rising from 208.2 ft-lbs to 315.2 ft-lbs at the wheels. The system delivers its strongest gains in the upper RPM range while maintaining smooth drivability for daily use.
The TruControl by STILLEN 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 different tuning maps, ranging from Eco to Race modes, enabling drivers to tailor performance to their driving style.
Custom over-the-air tuning files are available when used 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 risk-free testing in your own vehicle.
