Maybe PCP guns are like like car engines there's no substitute for displacement.

Its been done before iirc no added gains over a single bigger plenum.

Only so much air it can move before the projectile has left the barrel.

If you add a PP does it use more air per shot? Just ordered one for my FX Dreamline.25 but I’m only getting about 25 shots now.

If your not tuned on the down curve of the power for your regulator setting, it will use more air. A bigger plenum should add shot count. After installing a bigger plenum , you should reduce both the regulator pressure and hammer spring tension to match .

I have done it. It offers more efficiency or power.
