BMW Tune - Sprint Booster

The BMW Sprint Booster enhances acceleration by continuously measuring the digital signal from the electronic throttle control (ETC) potentiometer and sending a modified signal to the engine control module (ECM).

To put it simply, think of it like a 100-meter race: your BMW is the runner, and the Sprint Booster isn’t like a steroid that makes the runner faster. Instead, it’s like a tool that improves the reaction time from the starting gun to when the runner takes off. In essence, you’ll feel like your car is launching quicker and more responsively.
