I lost my restrictor when I installed my booscontroller..
After install I could not hold a steady boost .. so i clamped the preasure pipe and got good boost ...

The hole is the size of a normal straight pin, like a taylor or seamstress would use.
It goes in the hose to the pressure sensor to keep boost spikes from giving fuel cuts.
It is normally completely seperate from the waste gate line.

The stock boost control works by bypassing pressure before the waste gate line.
An aftermarket boost controller normally goes in the waste gate line, just before the actuator.
