ok. i posted a thread about this before but i still cant seem to find my leak. my boost gauge reads 0 at around 1000 rpm and when it revs up to 3000 it has -20psi. i have checked all the lines and they seem to be fine. but when it is at 3000 rpms i can head a really high pitch noise and i have had my dad look while it is making the noise but no luck. so i am totally lost and i don't really have the money to bring it some where to get it fixed. it started after i put my headers in. any idea on to find it if there is a step by step or anything that would be great.
