You should be able to wind the hammer spring preload in a couple of turns and perhaps, open up the transfer port a little. Other than that,┬áthere isn’t much you can do without modified springs and hammer weights. The hammer spring adjustment is located behind the plastic end cap on the back of the air tube. Clockwise will increase the preload. Forget about using a regulator. You will only get fewer shots and less power with the stock tune.
