S15 Silvia Boost Controll Solenoid

[sky30]

Does anyone know what the solenoid on the boost line to the wastegate actuator actually does??

How will boost be affected if this is removed, compared to if its hooked up?

it will be a limiting valve, closing to a smaller diameter in higher rpm.

this will let the actuator spike over a little, the affect it gives is like dual stage boost control. normal its say 7psi over a certain rpm, it closes and narrows the diameter and you get around 9psi. thats what the r33 one does.

So if i remove it and run a line straight to the actuator, will i be better off or not?

Will i get more boost, for longer without the solenoid??
