Description

The Speed-Buster Power Module Kit is a plug-and-play upgrade for the S55 powerplant. It safely and effortlessly extracts more power and torque from your engine. The module works by sending modified signals to the engine computer, safely raising boost levels without triggering torque limiters, monitors, or limp mode.
