Hey guys, what are your thoughts on upgrading the stock actuator to an adjustable Forge one?

I have a Polo GTI still running stock Ko3 that is I guess almost maxed out with a stage 2 custom code tune putting out 190hp and 380nm at the wheels. It hits peak boost at around 22psi now I have change the spring in the DV to the yellow one rated at 15-23psi. (it was peaking at around 18psi before with stock spring)

So my question is if I now change the stock actuator to an adjustable one with the appropriate spring rating will I hold max boost longer or see an increase in power or both?

Thanks,

Anthony.
