lights and tuning headaches associated with high flow exhaust systems.
Installs in the ECU area and is compatible with all BMW tunes and
chips. Available for the N54 twin turbo.
The JB4 tuning system includes this functionality built in so a DPFIX is not required if you are already running a JB4 Performance Tuner!
