POWER & PERFORMANCE

Stage 1 – 98 RON

Designed to deliver increased horsepower and torque using the factory hardware and turbocharger.

Hardware Requirements: None

Fuel Options: 95 RON / 98 RON

Transmission Software: Not required for full-output files

Option: Low Torque file available with a flatter torque curve and reduced low-end torque.

STAGE 1+

APR Stage 2

The APR Stage 1+ / Stage 2 ECU calibration is designed for vehicles equipped with the APR Intake System and APR Intercooler System, while retaining the factory turbocharger.

Hardware Requirements:

  • APR Intake System

  • APR Intercooler System

Fuel Options: 95 RON / 98 RON

Transmission Software: Not required for full-output files

Option: Low Torque file available with a flatter torque curve and reduced low-end torque.

ADVANCED ENGINE PROTECTION

APR's calibration incorporates multiple protection strategies designed to maintain reliable operation under demanding conditions.

These include:

  • LSPI and knock protection

  • Turbocharger shaft-speed monitoring

  • Turbo overspeed protection

  • Exhaust backpressure monitoring

  • Pressure-ratio protection

  • Active thermal management

  • Oil-temperature based power management

  • Fuel-system protection and optimisation

  • Corrected ECU sensor and protection models

The system continuously monitors operating conditions and can adjust power delivery when necessary to help protect critical engine components.

ENHANCED DRIVING EXPERIENCE

The APR calibration is designed to improve more than just peak horsepower.

Above 3,000 RPM, the exhaust valves can be commanded fully open to enhance the engine's sound and power delivery. APR has also introduced a subtle exhaust crackle inspired by previous RS3 models.

Additional calibration changes include:

  • Increased stationary rev limit to 5,500 RPM

  • Exhaust valves fully open during stationary revving

  • Enhanced exhaust crackle

  • Left-foot braking support

  • Brake boosting functionality

  • Speed limiter removal

  • Auto Start/Stop memory

  • Recalibrated boost, power and torque gauges for higher output levels

These features provide a more engaging driving experience both on the road and during spirited or track driving.

PERFORMANCE WITHOUT COMPROMISE

APR's ECU upgrade is engineered to provide substantial performance gains while retaining extensive factory-style protection strategies.

The calibration improves turbocharger control, boost management, thermal protection and fuel-system operation while delivering smoother throttle response and a stronger, more linear power curve.

The result is a more responsive RS3 with increased power throughout the rev range and improved confidence when driving under demanding conditions.

FREE SOFTWARE UPDATES

Eligible customers receive free software updates when APR releases new versions, adds standard features or when a vehicle manufacturer's update requires a corresponding APR software revision.

IMPORTANT NOTES

  • Software availability depends on the vehicle's ECU box code and revision.

  • The APR 30-Day Money-Back Guarantee has exclusions.

  • Hardware-bundled upgrades may have different guarantee terms.

  • Third-party labour, service charges, ECU unlock fees and core charges are not covered by the software guarantee.

  • Software updates are available to the original purchaser or through an eligible warranty transfer.

  • Third-party labour costs are not included.

  • APR Plus is not compatible with DIY options.

  • APR Plus availability varies by region.

  • Ultralink is currently not supported.

PRE-PURCHASE DISCLAIMER

For older or higher-mileage vehicles, a complete mechanical inspection is strongly recommended before purchasing tuning software.

Do not purchase tuning software if the vehicle currently has:

  • Engine or drivetrain warning lights

  • Existing running or performance problems

  • Misfires

  • Excessive or unusual oil consumption

  • Known mechanical faults

  • Any unresolved vehicle issues

If an inspection determines that the vehicle is unsuitable for tuning, additional charges may apply for the technician's assessment time.

Installing performance software on a vehicle with existing mechanical problems can potentially cause further damage and is not recommended.
