APR is pleased to present the ultimate engine control unit (ECU) upgrade for the Audi SQ5 3.0 TFSI V6. APR’s ECU upgrade is available in octane-specific variations and is conveniently flashed to the vehicle’s factory ECU through the OBD-II port without any physical modification to the factory ECU.

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 403 horsepower and 371 ft-lbs of torque with 93 AKI octane fuel. Large gains were seen throughout the power band, including an additional 50 horsepower and 43 ft-lbs of torque. Even higher figures were achieved using 100 AKI octane race fuel. The increase in power directly translates to an exceptionally quicker vehicle.

For those demanding more torque and power, The APR Supercharger Pulley Upgrade is the answer. Spinning the supercharger faster increases air flow allowing for higher boost levels and more power. The gain in torque is felt immediately, but the results are present across the entire powerband. Expect 419 horsepower 93 AKI octane fuel and 445 horsepower on 100 AKI octane race fuel! Software is included as a free upgrade for APR Stage I customers with the purchase of an APR Supercharger Pulley Upgrade.

APR’s ECU upgrade is the best power per dollar modification for the new 3.0 TFSI engine and takes the vehicle’s performance to similar levels typically reserved for higher output, sporty models, without pushing the limits. With factory-like smoothness and drivability, APR’s ECU upgrade will fill the void in an otherwise excellent vehicle. Read More!
