Does the factory boost control have a restrictor pill in the red tip pipe?

[Davezj]

Hi All,
i have never found one in any boost control pipe work i have looked at.
but i have not owned a VR4 from new so any of the previous owner could have removed it for some reason.

the restrictor pill is designed to limit the volume of boosted air that actually goes to the boost solenoid and the wastegate actuators.
It does not limit the boost pressure getting there just the volume. so when the boost solenoid bleeds off some of the pressure it is not immediately replaced by more boosted air which kind of works against what the boost solenoid is doing.

there is a restrictor pill in the entry port on the boost solenoid valve itself but this is not what i am talking about. i am talking about a restrictor pill in the red tip boost pipe before the T piece that splits off to the boost solenoid and wastegate actuators.

is there supposed to be one fitted in the standard factory pipework.
