Turbonetic Evo Wastegate adjustment

[Church]

The directions that came with the wastegate were not to good or at least i did'nt get much usefull info out of them. I have a mbc hooked up to the bottom port and the top port is open. I also did'nt change the spring. My question is should i change the spring and shims, do i need to? I plan on running about 22 psi. From what i understand the spring determines at what psi the wastegate opens so i would really want the heaviest spring in there correct? It should spool quicker with the wastegate not opening so early correct?

Just looking for some insight because ive looked just about everywhere and have'nt found any usefull info on this wastegate.
