Actuator setup properly?

Maybe the style of mapping?

Actuator set up I reckon, How many turns did you turn it to preload?
Also what colour spring have you used?

3 full turn back and both dv and actuator have yellow spring. Car made 220bhp and 257ftlb tq so power itself is about right just dont understand why drops off like that.
