The Ampd Throttle Booster adjusts your vehicles throttle sensitivity, which reduces that dead pedal feeling while accelerating. Late model vehicles are built with an accelerator pedal position sensor to control engine fueling. The Ampd Throttle Booster takes that stock signal of the accelerator and changes the mapping, which leads to a more sensitive throttle, giving access to more on-demand power. The addition of the Ampd Power Switch allows user to adjust throttle sensitivity settings on-the-fly.
