Subaru ej25 jumpy when setting off

Hi when raising the clutch at a junction to set off it doesnt feel smooth and feels like the engine wanting to stall what things can i look out for in the tune?

Iv a twin plate clutch btw

Thanks in advance

You probably need to make a couple of logs of those transitions with rpm, throttle, timing, AFR/Lambda visible for people to offer much commentary. The nature of some clutches is that they are much grabbier and abrupt in take up than factory sprung organics, even with a "perfect" tune you will still often get snatchy take up or driveline elastic whip. Some people will intentionally retard parts of their ignition map they only really use in that load state to reduce that effect.
