My P rod shoots JSB 18,1 at 25FPE with the original barrell,regulated at 2000psi,the port path is opened to .165 (transfer port,barrell and valve).Don't know your power objective,but maybe you can do some with a little valve work.Hillsairguns sells a Prod kit tough.
When striving for power, longer barrels almost always help....

I would love to put a bottle on my Maximus. Suggestions appreciated!
I have a similar setup,if you are looking for maximum power,a regulator is not the right way.my 13ci bottle setup is regulated a bit above 2000psi and shoots 18,1 pellets at 25FPE,to obtain more power the regulated pressure must be increased resulting in less usable air,the advantage in my setup is a flat string of about 60 shots,increase the regulator pressure above this point can reduce the shot count nulling the advantage of a bottled setup.
Typical rookie mistake on that bottled PRod in the video, IMO.... There appears to be very little volume between the gauge block and the back of the tank block.... ie no real plenum.... This severely restricts the FPE you can get at any given regulator setpoint pressure.... Ideally, if you want 25 FPE, you should have about 25cc of plenum.... A 3" space between the front of the gauge block and the back of the tank block insert in a PRod would be about 21.4 cc, which once you include the volume inside the gauge block and valve would be pretty close.... If you want more power, you should leave even more tube length between for more volume.... about 1 cc of plenum per FPE is ideal....Bob
I have been able to get over 25 fpe with the huma and its .25 plenum. Set at 1875 I could get right at 30 fpe. \Removed a 53 gram Challenger hammer and installed a 38 gram MSD and my fpe has plummeted. Just over 15 fpe. Going to see if Rocker1 one cam make up a hammer with a bit more weight. I know everyone and their brother goes light on the hammer. However, the hammer stroke on the Maximus is ridiculously short. Needs hammer weight, and or sporing to make any power.
