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

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.

Curious to this as well. I’d like to get that barrel at some point in the near future.
