I have barrels in .177 and .30, (.22 and .25 too). To those who know, do you think I should add the 2 optional plenums. Will any gains on the big caliber hurt the .177? Will I need to re-tune or will I just see a little higher velocity from my current tune?

Are you shooting pellets or slugs across all 4 calibers?
I’ve got two P1s (big difference as P1s have a much heavier hammer - 34g - and lack the balanced valve) and just shoot pellets - I’ve got a four calibers.
With pellets, stock plenum size is more than adequate even for .30 caliber. I don’t believe I’ve ever used reg pressure above just 120-125 bar to shoot 44 and 50g pellets in the normal 870-910 range.
If anything, I use a softer hammer spring for .177 (and 18.13 and lighter .22) to give easier cocking and more adjustability. Hammer spring not as important with your balanced valve - but lighter spring may be useful for .177.
Prophets make huge power - and in such a compact, minimalist form - great rifles.

I want to shoot slugs in .177, both in .22, .25, and .30 The cocking effort has not been a problem on my balanced valve gun. My gun is the standard, 600mm (except for the .177) with the 500cc bottle, not the Compact.
