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.

Product Features:
  • Reduces Throttle Response Time
  • Improves Acceleration
  • Easy To Install
  • Does Not Affect The Vehicles Electronic System
