I have several spritebooster's in stock, stage 1 which is one sprite bottle cap is $50 shipped and stage 2 is two sprite bottle caps glued together for only $95 shipped.
Installation is easy. Just glue or velcro it to the top of your switch under your gas pedal and your good to go.

I am now offering stage 3 for $115 on sale. This consists of 1 long stainless steel speed screw that screws your gas pedal to the floor so you are at wide open throttle 100% of the time. This mod is for the extreme speed racers only.
