Sprint Booster for Scion - $329.95

"I installed the Sprint booster I ordered today and what a difference. Although the unit does not give you any extra power the throttle response is insane and the car really takes off.

Installation was a snap and it comes with an optional remote that allows you to select between the off, moderate (green light) and race (red light) modes. In race mode the car launches every time you touch the gas pedal!

I was amazed how much difference this little gadget made. I'd recommend green for daily driving and and red for the weekends..."
