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 800psi

Black = .005 inches + 20psi
Silver =.010 inches + 40psi
Gold = .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.
