In just five minutes, without a single tool, you can plug-in the Throttle Performance Switch and get an instant improvement in throttle response. The switch plugs in line with the throttle position sensor to deliver the optimum and maximum amount of fuel and timing advance whenever you give your Corvette at least 60% throttle.
The seat-of-the-pants improvement works equally well on stock or already modified engines. Each switch is supplied with installation instructions and you'll easily locate the throttle position sensor on the top side of the engine on all 1982-1991 C3/C4 Corvettes.
This switch does not affect idle or emissions and is 50 states legal.
