For advanced tuning for plunger and tiller/brace height, I recommend checking out Tuning for Tuning for Tens by Rich Stonebraker and Bow Tuning by Ten Zone. Although both cover the same material both documents together create a great understanding of the tuning methods.
Lastly, is stabilization I recommend reading Going Steady by Andrew Smith. Andrew explains the principles behind using stabilizers, the various types available and how to set one up.
Remember changing one thing can affect the other components and the plunger is no exception. As an example, I changed to a new stabilizer long rod and ended up having to adjust my plunger to compensate.
Apply the simple rule of incremental changes all the while watching for reactions to the change. That’s the best way to tune a bow, in small steps… Be patience and test each change.
