Initially, to adjust the trigger settings, I would suggest setting your board to semi - it's going to be easier to work out what is going on.
As far as board settings are concerned - obviously the physical trigger settings such as pull length, weight, and firing point will also have an effect on trigger bounce - pull the trigger very slowly and try and hold the trigger at the point where the marker fires. If this leads to a full auto like burst, increase AMB. Keep testing and adjusting until the marker no longer goes full auto.
In the case of debounce, you need to increase the value until you never have more shots fired than trigger pulls.
With regards to PSP rate of fire, it really depends on what the maximum allowed rate of fire is where you are playing. If you are actually following current PSP tournament rules, the maximum rate of fire allowed is 12.5bps. I would suggest setting the board to 12bps (though in your case, this seems like the closest possible option anyway) to give a little buffer between your set rate of fire and the maximum allowed rate of fire.
