Ok, generally speaking, if you increase a gain setting the control should try harder to hit your setting. The control algorithm is a modified PID, which stands for Proportional, Integral, Derivative. I named the gains with more "human" names to try to make it more understandable.
There are some differences in the different software versions, mostly in the spool to run transition.
The unit attempts to calculate what the solenoid "base" dutycycle should be based on your target boost and solenoid settings.
Anyway, lets say you are cruising along and punch it. The unit switches into Spool mode, which kicks the solenoid on to 100% to help spoolup. As the boost approaches the target, the dutycycle is reduced back to the base dutycycle. Spool gain and anti-overshoot work here to get the boost up to the target as fast as possible. On these cars, the anti-overshoot does not do very much, the spool gain is the primary influence. Higher spool gain makes the dutycycle stay higher to try to get the turbo spooled.
once the boost gets close to the target, the anti-overshoot gain turns off, and the run gain turns on. (the spool gain is always on, but does not do much when close to the target boost) the run gain adjusts the solenoid dutycycle somewhat slowly to try to keep the boost at the target. Higher run gain will adjust faster.
For best operation, the solenoid characteristics need to be close, so the base dutycycle calculates close to the correct actual dutycycle, I will show you that in your log.
