GReddy® Cut Controllers permit the stock computer boost and speed cut limiters to be eliminated. This fixed-setting controller was engineered and calibrated for to work with specific makes and models. The box is connected directly into the factory computer's wiring harness. The new Speed Cut Controller removes the speed cut for most Nissans and Toyotas. An additional capability for the SCC is its speed trigger feature that can be used with future Greddy components.
