True Plug & Play Tuning

JB4 Group 10:

This easy to install plug and play tuner attaches to sensors in the engine bay and works with your factory ECU tuning to remap boost, timing, and fueling for optimal performance and reduced turbo lag. Includes full CANbus allowing the JB4 to access and incorporate all engine data in it's tuning strategies, incorporate unique safety features such as keeping boost pressure low until oil and water is up to temperature to provide proper engine and turbo lubrication, and drop to a low boost map if the engine starts to over heat, run lean, excessively knock, or over boost. Fully compatible with JB4 mobile for on the fly map changes, data logging, firmware updates, and much more. 


You may also wish to add the Data Cable or the Bluetooth Connect Kit for additional features.



The simple plug and play installation is very discrete and it quickly removes without a trace when needed.
