Jeff, Most PCP guns are adjustable to certain degree. Usually hammer spring tension. Increase the force that the hammer opens the valve and it lets more air out to push the pellet faster. Spring guns require more work. There are kits available for this or you can send the gun to an air gun smith. The Benjamin Marauder or (Mrod as it is affectionately called) is very tunable. A good place to learn about this is here: http://www.marauderairrifle.com/forum/viewforum.php?f=14&sid=a929448cebcce629ade97b6169002228
This will give you an idea of how most PCP's work.
