.35 FX M3 tune starting point with JSB Hades or JSB Diablo?

[owesme$]

Any thoughts on starting point for FX M3 Impact 800mm .35 with JSB Hades or Diablo? I know all guns are different but my buddy just got one and I was gonna try and start with some tunes from anyone on this forum who can give me some ideas. Thank you in advance. ( I posted in PCP section but no one answered except another member who wants to know the same thing.)

When I first started with pellets, I found the best accuracy between 850 to 880 fps. When they got going too fast they would spiral. If memory serves me correct, you can achieve those speeds with max hammer settings and a 130 to 145 bar setting on the 2nd reg.
