Factory ECU-Controlled Stage 3 Performance + Multi Port Injection (MPI) Fueling (MPI) • Proven 3.12s 0-60 MPH • 9.55s 60-130 MPH • For 2022+ VW Golf R, Arteon and Audi S3. Up to 527 WHP / 408 WTQ on E85.
The APR Stage 3+ ECU Upgrade for the MK8 Volkswagen Golf R and Audi S3 unlocks the full potential of the APR PowerMax GT2563S Turbocharger System and APR Multi-Port Injection (MPI) Fueling System. Developed specifically for the EA888 Gen 4 engine and Simos 19 engine control unit, APR's Stage 3+ calibration delivers substantially increased power and torque while maintaining the drivability, refinement, diagnostics, and safety systems expected from a factory-engineered vehicle.
Unlike conventional aftermarket fueling solutions that rely on standalone controllers or supplemental engine management systems, APR's Stage 3+ calibration directly integrates turbocharger control, fuel delivery, torque management, and multi-port injection operation through the factory ECU. The result is a seamless driving experience with exceptional power delivery, OEM-like operation, and repeatable real-world performance.
APR engineers spent thousands of development and validation miles refining boost control, fuel pressure management, ignition calibration, torque modeling, and driveline integration to create a complete Stage 3+ solution. The software works in conjunction with the APR PowerMax GT2563S Turbocharger System and APR MPI Fueling System to deliver true Stage 3+ performance capability while retaining the factory ECU architecture and comprehensive safety strategies.
Dyno-validated wheel output confirms real-world gains across every supported fuel from 451 WHP on 91 Octane up to 527 WHP on E85, with 473 WHP on 93 Octane, 491 WHP on 100 Octane, and 503 WHP on 104 Octane, delivering up to +212 AWHP over a stock 2022 US Golf R baseline.
