Hi guys im new to perth wrx. Bought an 02 wrx wagon last weekend. It has overboost issues. From what I can tell.. the turbo is stock.. the wastegate is stock.. it has a gfb atomic manual boost controller installed correctly.. and I cannot seem to find the restrictor pill in the line between the turbo and the boost controller.

How does all this add up to overboost for you guys in the know? Or can anyone help me troubleshoot to figure out why it is overboosting. Also the boost controller is wound right back to as lower boost level as it can go.

Please help guys its no fun having to only use half throttle to avoid overboost.

Thanks

Cameron
