    no power??

    hi everyone quick question. i have an 02 wrx and and like a dumy i put a BOV on it and it killed my power the i put the stock bypass valve back on and i still have that same loss of power. ive checked all the hoses and lines no leaks and ive reset the ECU by disconnecting the battery and mashing the brake at least twice. i was riding down the road the other day and my power just all of a sudden came back. and then a couple hours later it magically dissappeared again. i can hear my turbo perfectly so i know it works and i dont have a boost gauge. is the wastegate vacuum or electronically controlled? and is that where i could be loosing my boost from prematurely. if so what could i do about it. and could it be anything else. thank you

    invest in a boost gauge, and possibly an ETG as well. it will tell you alot more about whats going on. it sounds to me like you got some kinda boost leak or didn't put the manifold pressure line back on the BOV correctly.

    Agreed that it sounds like an incorrectly plumbed hose or a leak.

    Moving to Troubleshooting.
