How about up to 60hp to the wheels (80hp crank) on a completely stock car or up to 100hp to the wheels (120hp crank) on a fully modified car? The JB4 features a simple plug and play installation harness for easy installation and includes many features not found on any other tune. Including on the fly in dash map switching between factory and various performance maps, optional in dash gauge displays for boost and other critical engine parameters, progressive water/methanol support, ethanol fuels support, built in code reading, and much more.
Remember the JB4 does not require any additional modifications or previous stages. Simply install the JB4 as your first and only modification and enjoy an entirely new fast and smooth racing experience. The JB4 also does not require any user setup or customization but for more advanced enthusiasts the BMS DATA cable allows you to connect via a laptop for data logging and free software updates.
Right hand drive cars required a RHD extension for $30.
