The FAST Bump Stager module for XFI is a complete kit that lets drag racers pulse the transbrake to creep forward during staging for more consistent launches. It includes a built‑in 20‑amp driver to simplify wiring, and interfaces with XFI for adjustable ramp in/out times, output frequency and shift‑light control, providing precise staging control without requiring external relays in most installations.
