The reason your boost is bouncing up and down is because the stock WG spring is to soft, set at only 4lbs.
I stiffended the setup to 7lbs. I took a spring and attached it to the WG arm and the other end I secured it againts the brake line on the master. Make sure you put some type of rubber or something on one the end that yoru connecting to the brake line so you dont chaffe into it.
