its only there to make the boost more controlable. i dont think on the new cars they have them. maybe some else can shed some light?????

Yes i have found mine as per this on my old STI
The pills actually vary in size, the smaller the orifice in the restrictor the higher the boost, just bare in mind that if you swap out for a different size pill then car may need some sort of tweaking.
What scoob have you got?

Whos mapping the car? as i would suggest you speak to your mapper in regards to this as he/she will be able to define the boost for you and then that will relate to the restrictor. It;s just that i don't know the spec of your engine and don't want to advise you wrongly.
Or if you really want, a manual boost controller will override any restrictor pill and fool the turbo into more boost.
If i was in your shoes i would order a 0.8mm (if available), 1.0mm and 1.2mm pills and for the time being if the car is not holding boost then just use a 1.2mm to keep safe as these might get thrown out by the mapper.
But more than likely the mapper will not want to use a restrictor pill with the aftermarket ECU, as it slows down boost response. But speaking to the mapper will tell you all you need to know.
