I decided that I wanted to increase the throttle response but not go the tuner route, so I chose the Pedal Commander. This is a fun, dangerous toy! You can go from normal throttle body response to OMG mode by the push of a button! I also went the route of the bluetooth model as I don't want this device on my dash and can be completely controlled by my smartphone. Great device but watch changing modes while idling (doesn't support while moving) as it will throw a computer code if you change modes to fast.
