G series 520i with the B48 engine in for stage 1 CustomPro software while on 95RON fuel. Seeing power and torque increases from 1,800rpm onwards. As usual with the B48, these engines see huge gains from ecu software alone, to totally change how the vehicle performs. As you can see, this car left us with an additional 100hp and 118nm!!
