overshoot is normal when you fiddle with the settings until it sorts it self out. it surges up and down, maybe 3 psi total, so 1.5 above and 1.5 below say 16 psi. When i view the graph of the boost i can see it easily, and i can feel it. Is there a chart i should be using to adjust the boost ratio to achieve a certain psi? for example, i can adjust the gain and the boost settings to whatever i like, but for example, for 20 psi should i have the gain set at ten and the boost at 75?
