Bulldog .357 Tune question

[Kdub1984]

I have a .357 Bulldog
ported to .3125
Barrel polished
Pitbull power spring
Barrel supports
I’m slinging 152 KSI hp at about 900 fps generating about 270fpe
My question is what else can I do to get more out of it? Any input is appreciated!

Purchase a higher pressure air cylinder

That’s my next step, I am looking at the puppy power plenum from pitbull air guns. About as big as you can go. Thanks for the input!
