Help for fitting my EBC

[alundra]

Finally I founded how this piece fits like the GReddy profec B one.

The settings is hard to get.
Can you give me what number must be for my set up: large air filter, front mounted medium size intercooler, 2.5 piping, cold spark, stock healthy T2, 2.5 exhaust line.

My desired boost is 12 psi.

I need:

-Gain in %: ?

-Start boost: ?
star boost is at what psi the the wastegate begins to open, example if you boost setting is 10 psi and your start setting is 2 psi; the wastegate will begin to open at 8 psi

Thanks...
