GIAC Stage 1 Plus adds horsepower, torque and more throttle response throughout the power band. This calibration is compatible with vehicles that have no other upgrades to basic “bolt-ons”. The addition of a BMC high-flow air filter and exhaust system will increase overall performance.

Tuning is performed in-house via laptop through your vehicle’s OBD-II port.
