Been playing with my 2240 carbine. Its got an 18" barrel, Boss valve, Melon bolt probe and Disco heavy spring. These are some of the results I got
JSB 13.43 gr
Average of 639 fps for 12.18 FFE
Crosman 14.3 CP
Average of 629 for 12.5 FPE
H&N 14.66
Average of 624 for 12.67 FPE
JSB 15.89
Average of 606 for 12.961 FPE
JSB 18.13
Average of 578 FPS for 13.453 FPE
H&N 21.30 Cuda's
Average of 554 FPS for 14.52 FPE
Did not want to try anything heavier. Figured this 2240 is potent enough for taking squirrels from my yard.

That some great power from CO2! How many shots you get from a powerlet? What it needs now is a Powermax Hipac!

Still tuning it but getting about 12 shots before a significant drop in power. Hope to try the Hipac tomorrow.

So I played with the HiPac in this beast and here are some peak numbers
CP14.3 grain, 1200 PSI
693 FPS 15.25 FPE
CP14.3 grain, 1500 PSI
744 FPS 17.58 FPE
CP14.3 grain, 2000 PSI
795 FPS 20.07 FPE
Thats about as high as I cared to push this 2240 without pinning the valve.
Of course with the Boss valve shot count can be measured on a couple of fingers.

Wow, that's a hard-hitting 2240.
Hunting is a good application for it too, then you won't mind that you're not getting too many shots per cartridge.

and power adjuster and fill to 2000psi.

You should make some nice power with that combo. Just play with the spring pressure to tweak it.
