    It controls the Wastegate - Opens and closes it Via Vacum. (holds the boost in or lets it out)

      Uprated ones are stronger (stiffer) then the standard and so can hold higer boost pressures.

      If your going to be putting out high boost pressures then you might need one depending on what the standard one can hold.

        They just have an uprated spring inside... only worth doing if you are going high boost, or if your current one is weak (old- loosing boost)

        They are OK, but there are much better options out there

          You could always fit a "helper spring" which is an external fitting to your original actuator.
