APR Stage 1 ECU Chiptuning Software for 3.0L TFSI engines as built in the Audi S4 and S5 B8.

APR's Calibration Engineers spent months calibrating the engine management system, including many hours of chassis dyno development. With a thorough understanding of the ECU’s torque structure, APR’s Calibration Engineers properly increased engine load to produce more power and torque across the entire power band. APR’s ECU Upgrade increases boost pressure, optimizes ignition timing, cam timing, lambda and more to produce higher output!

APR’s ECU upgrades are one of the best horsepower-per-dollar modifications for the 3.0T 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 375 ft-lbs of torque and 441 horsepower with 93 AKI octane fuel. Large gains were seen throughout the power band, including an additional 72 ft-lbs of torque and 98 horsepower. Even higher figures were achieved using race fuel. The increase in horsepower and torque directly translates to an exceptionally quicker vehicle.

For those demanding more torque, The APR Supercharger Pulley Upgrade is the answer. Spinning the supercharger faster increases air flow and allows for excellent gains over stage I alone. The gain in torque is felt immediately, but the results are present all the way to redline adding up to 82ft-lbs and 112 horsepower with 93 AKI octane fuel! Stage II Software is included as a free upgrade for APR Stage I customers with the purchase of an APR Supercharger Pulley Upgrade.

Features Stage 1 Software:
- up to 455 hp
- torque 533 nm
- upgrade of other APR Hardware included

Please send your ECU to us after purchase.
