On the stock PM7 board it's called the eye sensitivity setting. Raise it up a couple milliseconds. That should help. I used to set my guns up by putting 10 balls in the hopper and then ripping them out. If I broke one, I'd up my eye sensitivity another millisecond. Then repeat until I could fire all the paint out. This can help you prevent ball breaks during those intense games when your hopper runs low as well.
