Sharpen throttle response with the Dinan Throttle Booster, an electronic throttle controller designed to reduce the delay between accelerator-pedal input and throttle response. Dinan positions the unit as a way to make modern electronic throttles feel more immediate without changing engine calibration.

The Dinan Throttle Booster offers multiple selectable response settings so the driver can tailor throttle sensitivity to the vehicle and driving situation. It is designed for plug-and-play installation on compatible applications and does not require permanent engine modifications.

Dinan lists this throttle booster for approximately 2000 and newer BMW applications, approximately 2002 and newer MINI applications, and 2020 and newer Toyota GR Supra applications. Dinan's current official listing identifies the part as D440-1700.
