I think you're a little confused. Yes the actuator will affect the boost, but the easiest and cheapeast way is to add boost control. In it's simplest form a bleede valve. With the standard metro actuator, you should be able to bleed off enough signal for 15psi.

The arm needs to be set for pre-load, that is you need to pull it to fit ot over the wastegate arm, this ensures that the wasetage is held shut. If you have standard CR then you should be able to run 10 or 12psi with a decent IC, but slightly lower CR is always safer. Easiest way is to get the head chambers modified.

Remember, you need to consider the fuelling when upping the boost, if it runs lean, your pistons will melt.
