Sprint Booster V3 for Lexus GS430 2001-2004

The second-generation GS, chassis S160, was the sporting Lexus sedan of its time, and the GS430 version carried the 4.3L V8. This page covers the US 2001 to 2004 model years. The electronic accelerator in these cars is tuned conservatively, which blunts the punch of an otherwise quick rear-drive sedan.

Restoring the punch

Fitting a Sprint Booster lets the GS430 behave like the sport sedan it was meant to be. The module amplifies the pedal input so the throttle opens sooner, sharpening launches and roll-on acceleration. Power output does not change because the V8 programming is never touched.

Many GS430 owners keep these cars as rewarding weekend sedans, and the Off setting means the car can still be handed to a family member with its original manners. Switch to Sport for the commute and Race for an empty back road.

GS430 fitment

Everything happens at the accelerator pedal plug. The supplied connectors mate with the Lexus harness, the selector goes where you can see it, and the job is reversible.
