WARNING: This product can expose you to chemicals that are known to the State of California to cause cancer, birth defects or other reproductive harm. For more information, visit www.P65warnings.ca.gov.The APR Power Control Unit (PCU) is a sophisticated inline tuning solution for the Mk8 GTI (EA888.4 2.0T). Designed as a high-performance "piggyback" system, the PCU connects to your factory sensors to safely increase boost, fueling, and timing without overwriting the software on your vehicle's factory ECU. This makes it an ideal choice for enthusiasts looking for significant power gains—up to 41 HP and 50 FT-LBS at the wheels—with the ability to revert to stock simply by unplugging the hardware.
The PCU offers unparalleled flexibility through its dedicated smartphone app (iOS and Android). Users can toggle between five performance levels, ranging from 87 octane-specific maps to high-output premium fuel settings, and even adjust throttle sensitivity on the fly. To ensure engine longevity, the unit features built-in thermal protection that prevents increased power delivery until the engine is up to operating temperature, or if it begins to exceed safe thermal limits.
Features:
- Instant Power Gains: Adds up to 41 HP and 50 FT-LBS of torque at the wheels on the Mk8 GTI.
- Warranty Friendly Design: Does not flash the factory ECU; simply unplug the unit to return the vehicle to a completely stock state.
- Adjustable on the Fly: Change between 5 power levels and adjust throttle sensitivity via the APR smartphone app or optional Bluetooth controller.
- Smart Protection: Internal safeguards monitor engine temperatures to ensure power is only delivered when the vehicle is in a safe operating range.
- Versatile Compatibility: Supports 87 octane (Level 1) through Premium fuels (Levels 2-5).
- Diagnostics Tool: Built-in ability to read and clear engine fault codes directly through the app.
- Non-VIN Locked: The hardware can be removed and transferred to another compatible vehicle in the future.
