so in theory, lets say you just brought a new actuator, you could set it up yourself, if the car runs slow, you havent wound the boost up enough and if the boost limit comes in its to high, as it said further up, the max for a standerd ecu is 10psi, and a standerd rs is ok to run 12psi safly, so 10psi should be fine, is this a way of setting up your acuator?
