How does the Sprint Booster improve acceleration?

Modern cars use electronic throttle control (ETC) which can create a delay between pressing the pedal and the engine responding. The Sprint Booster plugs into the accelerator pedal's connector to bypass this delay, making acceleration feel more immediate and crisp.

Can I adjust how aggressive the throttle response is?

Yes, there are three main modes: Stock, Sport, and Race. Within Sport and Race modes, you can select one of nine programs, allowing you to fine-tune the throttle response to your preference, from mild to very aggressive.

Does this affect my car's ABS or other safety systems?

No, the Sprint Booster is designed to only modify the accelerator pedal signal. It does not interfere with other vehicle systems like ABS, electronic fuel injection, or the engine control module (ECM).
