Im running about 13-14psi boost and my settings are

Gain 10%
Set Gain 15
and the adjustment u make by just turning the knob and not in the menu ive got it set at 65% (i just use that to change the boost psi)

You can also try these...

Similar to my settngs, but my set gain is closer to the actual boost level... i am running 17psi and my settings are

Set=83%
Gain=10%
Set Gain= 160

Holds boost perfect, no spikes and no drop off.
