How does the Sprint Booster improve acceleration?

The Sprint Booster changes how your electronic throttle pedal signal is sent to the engine. It reduces the delay inherent in drive-by-wire systems, making the car feel more responsive when you press the gas.

Does this add horsepower to my Audi?

No, the Sprint Booster does not add horsepower. It modifies the throttle pedal's signal to make the existing engine power feel more accessible and react faster to your inputs.

Can this be shipped to California?

No, this part is not CARB approved and cannot be shipped to California due to emissions regulations.

About this part

Product Details

Automobiles in the 21st century have replaced the more conventional throttle cable technology for an ECM (Electronic Control Module) that translates pedal travel into electronic signals in order to provide power to the wheels. The ETC system (Electronic Throttle Control) – also known as drive-by-wire – has the unfortunate downside of delayed throttle response and subdued acceleration, creating problems in certain circumstances such as up-hill starts, quick gear changes, overtaking, etc. The Sprint Booster aims to overcome this throttle response delay for ETC-equipped vehicles, providing crisp on-tap acceleration at the driver's disposal.
