The suggested process is to first tune your PolarStar setup to your desired FPS (Feet Per Second) and PSI, then insert the lowest polarstar shims (Pink .015) and record your results, gradually moving to thicker shims until you notice a velocity drop, then revert to the previous size. This methodical process ensures you find the most efficient shim size for your specific build.
