You cant have a standard one running 22psi!
The factory ecu reads the level of torque being put out and adjust the boost pressure so that the torque figure is what it should be!
e.g. If the torque reading goes substantially above 450nM then the boost level is reduced. If the torque goes substantially below 450nM then boost pressuree iss increased to compensate and to get the amount of torque back to what the factory specified.
