2023+ GR Corolla Boost Control

The factory GR turbo comes integrated with an electronically controlled wastegate actuator - a simple boost controller will not work with the stock turbo, but if you've stepped up to a turbo kit with ECU tuning, we offer manual and electronic boost controllers and solenoids to get the job done!
