Unless you replace the piston with a flat-top there is no way you can over pump that gun....

Only up to a point.... With an otherwise stock gun, you will gain about 10% with 14 pumps compared to 10.... but it will take 30 pumps to gain maybe another 10% and after that you will gain virtually nothing with the stock pump....
