The Dinan Throttle Booster is a plug-in accelerator pedal module that sharpens throttle response and reduces factory throttle lag. It connects inline at the pedal harness and leaves the OBDII port free, installs in about 15 minutes, and is fully reversible. A wireless control switch and companion iOS and Android app provide five preset throttle curves plus thousands of adjustable settings, with up to three custom maps stored on the device. It works on stock or modified BMW, MINI, and 2020 and newer Toyota GR Supra models.
