O-ring Mod for Hammer bounce Discovery/Maximus

I have the maximus cal 177. I really need some help from you guys:) what is the o-ring mod? I could use some more fps and thought about buying the huma regulator and turn max bar. 

Please give me a link to o-ring modding and hammer,hammerspring.

If i use the huma air regulator install it with 150bar setup, will my fps increase with higher preasure or am i wrong? 

Sorry if my english sucks, i come from denmark
