BSR introduces a new concept – average power – to better illustrate the difference you will experience when tuning your car! BSR’s stated average power is equivalent to the average power increase within a given rpm interval. The rpm interval normally used in a petrol car is 2500rpm - 6000rpm, and for a diesel car 1500rpm - 4500rpm. The average power is calculated on these intervals.

Indicating the average power increase, and not only the peak output, is a better way to illustrate how the car will behave with BSR’s tuning. During acceleration, for example when overtaking, it’s the area under the power graph in the current rpm interval that determines how fast the car will accelerate. BSR’s stated average power generally tells more about the acceleration than the stated peak output.
