Hi everyone!

I'm new here, just bought a 850 Airmagnum Hunter from Germany (I live in Sweden). The problem is they have a 7.5 joules (5.5 ft/lbs) limit but we are allowed to have 10 joules (7.3 ft/lbs). I'd like it to be more but that's not really in my power sad.gif
However, I'd like to modify the valve to increase the power from 5.5 ft/lbs to 7.3 ft/lbs, does anyone have an idea what I should try?

Thanks in advance happy.gif
