The more you increase the reg pressure the harder the valve is to open, simple as that.  You need to add more hammer spring tension as you raise the reg pressure to see an increase in velocity?

Agreed, here's a picture of my impact, the crown is similar except you have to remove the stock. Insert an allen key shown in green and extend (turn in) the Allen screw to reduce the amount of play in the black floating rectangle. This will increase your hammer spring. Be sure not to adjust your regulator above 150 bar as it will likely cause it to seize up or damage it. Keep in mind those little manometers are not very accurate so I wouldn't get too close to the 150 mark.
