APR Stage 3 (OEM) ECU Upgrade for the MK8 GTI!

02/07/2024

We're excited to announce our Stage 3 OEM Engine Control Unit (ECU) Upgrades are now for the Volkswagen GTI (MK8) 2.0 TSI EA888 Gen 4 engine with the Continental Simos 19 ECU! This tune is designed for use with the larger OEM Continental turbocharger found on vehicles such as the MK8 Golf R / S3 (8Y). Expect massive gains with up to 410-478 HP with 400-443 FT-LBS of torque on tap, depending on octane and mods! This represents up to 111% more horsepower at the wheels, over stock, all without touching the factory exhaust system, fueling system, or any sensors!
