The main advantages of the electrical wastegate valve compared to the pneumatic wastegate valve are:
- High adjustment speed
- Precise boost pressure control
- High closing force, thus less leakage and quicker build-up of boost pressure
- Complete opening of the wastegate valve possible (This supports quick heating of catalytic converter upon cold start)
- Lower exhaust emissions
- Fuel economy
