i'm pretty sure you will be running some high boost , so please don't go all out.
See what boost it reaches , if higher than 0.55 bar ( assuming it is standard ! ) then make the rod of the actuator longer until you have your boost right.
I've put my original rs turbo actuator back on as i'm running 0.6 bar and its a pain in the ass to get 0.6 bar with a -31 actuator it will always end up with 0.7 bar.
Just so you know
