Equipped with 5 Throttle Performance Modes that the driver can select to best suit their driving style or needs. Set your throttle response from stock performance to wide open in the matter of a few clicks on your controller. In addition, there is a Valet Mode that reduces the throttle performance for the parking attendant and a Security Mode that stops the throttle from functioning at all.
