Hi! No you don’t need to purchase any hardware for APR Stage 1 as the tune safely maximises the capabilities of the existing factory hardware. This ensures that your vehicle does not require any modifications that may catch the eye of the local law enforcement but still get the gains that are present in your marques’ higher end vehicles.
APR’s ECU upgrades are one of the best horsepower-per-dollar modifications for your engine. The APR Stage I ECU Upgrade is designed to work without requiring other changes to the vehicle’s hardware. With the ECU Upgrade alone, APR’s Calibration Experts measured higher peak figures of torque and horsepower. Large gains were seen throughout the power band, including additional torque and horsepower. Even higher figures were achieved using race fuel.
Of course, when you’re looking at adding additional APR hardware. The APR Stage II software takes performance even further!
