This is a plug and play tune available for turbocharged vehicles. The Speedtune tuner installs between your car's sensors and its DME/ECU (computer) and manipulates vehicle performance through these connections making your vehicle much faster. While it's not the only tuning system that operates this way the Speedtune separates itself from the competition with much more advanced connection points and processing including CANbus, fuel & spark control, bluetooth to your smartphone, and a variety of innovative and advanced features not possible with any other system. Speedtune regularly publishes free mapping and firmware updates adding performance and features as ongoing development allows. In addition the Speedtune system is not VIN locked to your vehicle and can be quickly removed without a trace and swapped between cars or resold at a later time. Often imitated but never duplicated the Speedtune has been the gold standard in plug and play turbocharged performance tuning for over a decade.
