Default wastegate springs- need more boost

hey yall im looking for some more boost- i was wondering- my turbonetics 38mm evolution wastegate comes with 3 springs and some shims-

can i put to springs in together to make 12psi- i got the 8 psi spring in right now can i put the 4psi and 8psi spring into together? or should i just stack the shims

do the shims just add 1psi each?

why don't you just get an boost controller?
first off, install the red spring if you have it. red=9psi
2or3 shims=1psi, and i think 5 comes with the kit...so if you have
everything that came with the kit you should be able the push 11psi maybe 12psi if you're lucky.

oh and before i forget...the evolution is 35mm not 38mm

I would call up the guy who sells the turbo and/or the springs, to be sure
I'm getting the straight story as to what's going on with the springs.

Is there something else you need to do as boost goes up to be sure the engine doesn't blow?-Bob
