Sprint Booster V3 for Lexus SC430 2002-2010

The Lexus SC430 is a retractable-hardtop grand tourer that arrived in the US for the 2002 model year and stayed in the lineup through 2010. Every example uses the 4.3L 3UZ-FE V8 with a drive-by-wire throttle. Lexus set the pedal up to feel smooth and quiet, which suits cruising with the roof down but can leave the car feeling slow to answer when you want to pass.

A quicker-feeling SC430

The Sprint Booster changes the speed of the pedal signal rather than the engine itself. With it fitted, a small press produces a bigger throttle opening, so the V8 picks up the instant you ask for it. Highway passing and pulling away from a stop both feel more eager. Fuel and spark tables remain the Lexus originals.

SC430 installation

Connect the unit at the accelerator pedal connector inside the driver footwell. The plugs are keyed to the Lexus harness, so it fits only one way. Mount the selector somewhere visible, and you are done; unplugging it restores the car.

Features

• Pick original response, Sport or Race at any time
• Nine Sport and nine Race levels
• Matched to the five- and six-speed automatics used in the SC430
• Valet mode limits throttle when the car is with a valet
• Pedal Lock blocks the accelerator as a theft deterrent
