Johnston Research And Performance (JRP) has hooked me up with the new Sprint Booster v.3 to test. I was skeptical at first, but I discovered that I really like it. The super fast throttle response is very welcome in a drive-by-wire car. Downshifts are where it will make the most difference for me on the track. I also test the valet mode and pedal lock mode.

To clarify, this device amplifies the signal of the throttle pedal, allowing you to get to full throttle quicker.
