The shock dyno measures damping force over shock piston velocity so that a good estimation of how the shock will react under all driving conditions can be obtained. Speeds of 0-3 inches per second are low-speed damping and control body movement. Speeds of 3-6 inches per second are mid-speed damping and control larger body motions that the driver usually perceives as float. Speeds higher than that are considered to be high-speed damping and affects how bumps are absorbed or curb hits.
The shock tuners tailor the dyno curve to give the shock the response that is appropriate to the car, tire combo, and the driver's preference by making changes in the shocks valving to affect the curve.
If you are so inclined and want to spend the money, Feal can easily build you some sophisticated world class 2 and 3-way adjustable dampers. They can easily be built using Feal's basic knocked down kit but adding the additional modules for adjustment.
