Description
The aFe Sprint Booster V3 Power Converter (AFE77-16504) for the 2008–2021 Lexus LX570 with the V8-5.7L engine improves throttle response, acceleration, and overall drivability for vehicles equipped with electronic throttle control (ETC). Designed for plug-and-play installation, this ultra-compact device allows drivers to fine-tune throttle behavior for street, track, or daily driving.
Key Features

- Ultra-Compact Device – Mounts conveniently inside the cabin.
- Three Acceleration Modes – Off (factory), Sport (green LED, +30% throttle response), Race (red LED, +60% throttle response).
- 18 Customizable Acceleration Programs – Nine programs per mode; adjust aggressiveness using arrow buttons.
- Valet and Pedal Lock Modes – Limit acceleration or disable pedal function with a 3-digit PIN to prevent unauthorized use.
- Designed for automatic transmissions.
- Improves throttle response, transmission shifts, and drivability under various conditions.
Performance and Technology
Modern vehicles with electronic throttle control (drive-by-wire) often experience delayed throttle response and reduced acceleration. The Sprint Booster V3 overcomes these limitations by modifying the electronic signals sent from the accelerator pedal to the ECM. The device allows instant, precise throttle actuation for:
- Quick overtakes and smoother passing
- Improved hill starts and gear changes
- Enhanced automatic transmission performance
User Customization:
Each mode allows fine-tuning with 1–9 levels of aggressiveness. Valet and Pedal Lock modes provide additional security for vehicle operation.
