its been awhile since ive messed with mine, around 35-40% duty and i think 2% gain was what i ended up with. i need to get out there and retune to 12psi. i have an electronic boost gauge this time around too! i know autometers tend to be off slightly.
and when you tune seriously start at 10%duty and zero gain to avoid possible explosions. i think it took me 3 tries to get it dialed in perfect, its pretty easy to do. read the instructions ovcer a couple times and it starts to make sense.

using duty cycle only will not hold the desire boost at high rpm, Once the max boost disired is set with the duty cycle only then start reducing duty cycle and raise the gain. every -5% duty cycle then +2-3% on gain. for example I wanted 12 psi, I had 45% duty and 5% gain, car would spike to 12psi then higher rpms drop to around 10. Now I have 36% duty cycle and 25% gain now boost holds at 12psi.
