    No - the boost is ecu controlled. It will not matter which actuator you fit, you will still only get the boost the ECU map allows. Also, fitting an over strong actuator may make things worse, not better.

    Rich - you are right, I do know.

    The actuator controls the mechanical boost the system can produce. The ECU then controls the actuator to maintain the ECUs preset maximum. When increasing the ECUs preset maximum, you need to make sure the mecahnicals can reach that. This is done by adjusting the actuator. In the case of very high power setups, the standard actuator may not be able to hold the pressure the ECU is mapped to maintain - this is when a stronger actuator is used.
