so im looking at this diagram

i know a lot of diagrams
says to do the 2 port 1 solenoid vent method 1 turbo diagram (number 1)


im asking whats the diagram 1 vs diagram 2 vs diagram 3
can anyone explain pro cons?

reason i ask is im only going for 375-450whp
so mediocre goals

but also i dont have a nipple on top (wg) only the side. ofc i will go buy one if it really is that important
but for such low goals is it necessary?
