p-box setup: How to configure your p-box

Hello everyone! I own an analog HOPA-Divo P-Box. I would like to know how to adjust the three potentiometers to achieve more power/torque and a smooth engine running. The P-Box has a 'T' potentiometer for turbo, an 'S' potentiometer for vacuum, and a 'G' potentiometer for base load. Additionally, the P-Box has a connection for the airflow meter. It would be really great if someone could help me. Thank you!
