Compact Impact mk3 tune

[jpgf]

Looking for accuracy tune numbers for a compact Impact Mk 3 shooting jsb 25.39 redesigned
Don’t want to change to longer barrel setup and figure someone’s figured out. I’ve not been successful as of yet
Thanks

Regs like yours. Macro 16 and micro around 4 and valve same. 830 absolute max even playing with micro and valve. Are you getting good accuracy with yours? I’m talking consitent 1/2” (+,-) at 50 yards

im shooting 18 gr not 25 gr if i shoot 25 gr they are still good but poi is low of course 18-16 way better
