hey fellas, just got my 22 cal avenger pup set up for the JSB 25.4gr pellets at 830 fps with an insane tight extreme spread. however, 830 fps is the most and I mean absolute most I can get out of the gun. totally fine with that, plenty of power and accuracy for what Im using the gun for, but is that about what you guys are getting? I feel like ive seen higher FPS with this gun and those pellets. there's nothing wrong with my gun in terms of hammer spring or reg issues, I am shooting at about 40 degrees F so maybe that has something to do with it, again, perfectly happy with the 830 fps, just curious :)

at that time I had it reg'ed at about 2600 psi, I didn't notice much difference in velocities going any higher on the reg pressure. I shot it today and retuned the gun to shoot the 18.1gr at 913 FPS (random number but it shot 4 dupes in a row)

You can add a plenum also:

Air Venturi Avenger Oversized plenum

This is an oversized plenum for the AirVenturi Avenger in all forms. Fitment is straight forward but the stock will have to be cut or clearanced in order for the plenum to fit into or through the stock. My .25 Avenger with this same 10cc plenum is currently shooting 29 grain slugs at 990 fps...

Check the movement of the hammer. Make sure it moves freely. Also check the hammer spring. I have the avenger older brother liberty. The HS in it lost some of it strength and the hammer wouldn't move very good which killed the power. My liberty is capable of putting out 52 fpe but I've modified the heck out of it including a 18cc plenum.
