The Clubsport has the same tune as the Leon Cupra 290 and mist rolling road figures I’ve seen show it at around 300PS.
It would be nice if it was possible to flash the CSS 310 tune though.
A custom mapped ECU could give you sensible power and not so much torque that the front wheels just light up all the time.
A JB1 is a good option. It’ll keep the torque to sensible levels before overboost kicks in. Power is no good if you can’t transmit it!!
