The hill airgun parts are already precision machined and matched up for the best results.
You can set the tune for the power level and shot count you prefer. For example, in .25 caliber and using a 3000 psi fill pressure, shoot 25.39 grain pellets at around 900 fps for about 25 shots (more power uses up the air supply faster), or shoot the 25.39 grain pellets at around 773 fps for around 65 shots (very quiet shooting tune), or tune for something in the middle (compromise between power and shot count). 40+ shots at around 840 feet per second with 25.39 grain pellets is a very popular tune.
Excellent for pellet Or slug shooters.

Handheld deburring / reaming tool.
This tool is the Best option I have found to easily remove the sharp edge on the inside of the gauge port opening. To prevent air leaks, removing the sharp edge keeps the o-rings on the valve assembly and the gauge port from being nicked during their installation.
