This is for my S70 T5, i am running a Tim Williams map which is set to 19psi, i have recently replaced the actuator to a forge one however with the current spring (unknown) on part throttle the boost is bouncing around, however if i lower the boost to 15psi its stable on any throttle position.
Can anyone advise me on which spring i actually need for a stable 19psi please
thanks
