Overview

Ready to take your M5 to the next level?


Our latest tuning kit the F90 //M JB4 takes every thing that is great about the 2018+ all wheel drive F90 platform and amps it up to the next level. Power gains of up to 80whp and 100wtq bring the car to life allowing 1/4 mile potential deep in to the 10s. Unlike other generic tuning devices the JB4 includes full CANbus integration via the OBDII port for advanced tuning, safety features, and diagnostics, as well as electronic wastegate control for superior boost targeting. This is simply the best tuning box available for your //M.

Installation is fully reversible attaching to the TMAP sensors and OBDII port. The included electronic wastegate (EWG) wires are optional and allow the JB4 to take direct control of the wastegates for more precise boost targeting for higher boost maps. Firmware update loaded via JB4 Mobile or a BMS Data Cable will be provided free of charge as we expand the JB4's performance, maps, and features with future development.
