The JET SCU-2000 (Speed Control Unit) modifies the vehicle speed sensor output readings to correct your speedometer and odometer after making gear ratio or tire size changes. Shift points in automatic transmissions are also corrected. As a bonus the SCU-2000 also removes the top speed limiter! The unit installs with simple plug-in connectors to the transmission output speed connector and is easily calibrated by adjusting the dials.
*Available for 1996-Current GM Trucks and some 1994-2002 GM Passenger Cars.
*The SCU-2000 is only available for automatic transmissions.
