The Fuel Cut Controller allows the Turbo II to run at higher-than-factory pre-set turbo boost pressures without experiencing pre-programmed rear rotor fuel cutoff. The Fuel Cut controller essentially deceives the ECU (computer) into thinking the boost is not as high as it actually is. Consequently, the stock boost gauge no longer displays accurate boost pressure.
