COBB Tuning Stage 1 Power Package to NexGen Stage 2 with Flex Fuel Upgrade for GR / GV Subaru Impreza WRX STi

The transition from the COBB Tuning Stage 1 Power Package to the NexGen Stage 2 with Flex Fuel Upgrade for GR / GV Subaru Impreza WRX STi marks a significant evolution in performance for enthusiasts of these iconic vehicles. Initially, the stage 1 power package offers a foundational upgrade, integrating essential components like a high-flow air intake system, improved exhaust components, and a recalibrated engine control unit (ECU) map to optimize power and drivability. However, with the flex fuel Upgrade incorporated into the NexGen stage 2 package, the vehicle’s capabilities are further enhanced. This upgrade allows the engine to run on a blend of gasoline and ethanol, providing increased horsepower and torque gains across the entire RPM range while ensuring improved fuel efficiency and throttle response. Meticulously engineered for compatibility with GR / GV Subaru Impreza WRX STi models, COBB tuning continues to demonstrate its commitment to performance excellence, offering enthusiasts a seamless pathway to unlock the full potential of their vehicles on both the street and the track.
