Unleash the rally-bred performance of your Subaru WRX STI with this comprehensive Stage 1 tuning package. Specifically calibrated for models equipped with the Denso 68HC16-based ECU, this package offers a significant boost in power and driver engagement for an otherwise stock vehicle.
This package provides two distinct tuning options to suit your preference. The first is a pure Stage 1 performance file, designed to optimize boost, fuel, and timing for a substantial increase in horsepower and torque, transforming your driving experience. The second option includes the same powerful Stage 1 calibration but adds an aggressive Pop & Bang (crackle on overrun) map, delivering the signature sound of a rally car. Both files have been carefully developed to provide reliable power for your legendary STI.
