10Hz base.
ECU controls the PWM by varying from around 10% - 90%.

Stu and Tony are both correct.
The frequency is setable in the software for anything as low as about 3hz to around 60hz depending on your application.

So does that mean that the ECU can adjust the boost steplessly? Didn't know it was that advanced. I was under the impression that it was a simple solenoid (on/off).
