you cant copy other peoples settings, its different for every car.
start with the gain and set gain set as low as they go, and set the limiter 3-4psi above your target boost and the % limiter thing down low. then start winding the boost up til you reach close to your target. then wind in gain until it spikes then back it off a touch. after all that set the start boost (set gain) to 2-3psi below your target boost, if it spikes set it a bit lower.
if all else fails, find somewhere in your area who knows what they're doing to have a look for you
