The Output pressure of the Guerrilla Air G3 and P3 regulators can be adjusted with the use of shims (these are the only guerilla air regulators that use shims). Your regulator comes either fitted or packaged with three different sized shims. The amount of increase in pressure will depend on the size and combination of shims used. As standard the G3 and P3 regs starting output is 800psiBlack = .005 inches + 20psiSilver =.010 inches + 40psiGold = .015 inches + 60 psi Warning: Do not install more than .050 inches of shim in the G3 or P3 regulators. Installing more than the maximum recommended thickness will void your warranty and could cause irreparable damage to equipment. If you are not capable of working on your regulator please take it to a qualified air smith for service.
