restrictor pill

i have an 02 wrx with a tbe, intake, and mbc, when i bought the car it would only boost to .05 bar so i messed around with it some, and thought my boost controller was fried so i bought a mbc, now ive come to realise there was never a restrictor pill in the vacume line so figure now that is most likley the reason why it never had the correct boost. so does anyone kno where i can find a restrictor pill? can i just use any old brass bead?



thanks

You cannot use any brass bead. The hole that is machined in the restrictor pill is to precision and works with the wastegate duty cycles and the ECU. A slight change in the size of the hole will cause drastic boost changes.

The best place to get one is the dealership.

Just get a 3port BCS with a tune and forget the new pill, and also get rid of your MBC in the process.
