The APR Stage 3 System for the 2022+ Volkswagen Golf R and Audi S3 is the ultimate evolution of the EA888 Gen 4 platform - combining Garrett PowerMax GT2563S turbocharger support, APR's Multi-Port Injection fueling, and APR's Stage 3 ECU/TCU calibration into one factory-ECU-controlled ecosystem. The integrated MPI system works alongside the factory direct injection system under full ECU control, delivering the fuel capacity needed for true Stage 3+ power without a standalone controller. Available in 350 WTQ and 400 WTQ configurations with support for 91, 93, 100, 104 octane, and E85, the system has been validated at 3.12 seconds 0-60 MPH, an 11.16-second quarter mile at 123 MPH in full street trim at 3,000 density altitude - with 10-second capability at sea level - and 9.55 seconds 60-130 MPH, all while retaining OEM-style cold starts, drivability, and factory safety strategies. Dyno-validated wheel output 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.
