The aFe Sprint Booster power converter eliminates the factory throttle delay built into electronic-throttle (drive-by-wire) systems. It plugs inline at the accelerator pedal connector and offers selectable maps — a Sport setting for up to ~30% quicker response and a Race setting for up to ~60% — with no cutting, splicing or tuning required.
