boost low Options

ok my problem is that my boost is not reading what it should. When I first got the swap done boost would be about 8lbs in 1st and 2nd and about 11-13lbs in 3rd 4th and 5th gear now I have 8lbs in 1st 2nd 3rd and 4th gear and 12-13 lbs in 5th only. The power is missing from what I had. because of the lower boost. now I had a mbc and had it set to high for maybe 2 miles and hit 17-18lbs pretty much ran open boost but not for long I hit fuel cut and removed the mbc. Now I have lower boost, is my turbo going out? The boost takes longer to build now also. can my acuator be bad? tvis bad?

No its not a boost leak, because I had 2 solid pipes made I had boost leaks with my old fmic pipe kit with couplers and elbows but now its 2 solid pipes connected by couplers to the tb,turbo and fmic and there double clamped with t clamps so I am 99.9% sure there no leaks. how many lbs do you lose on a ebay fmic can it be 1-2 lbs I know theres a presure drop when you get get a fmic. And my turbo sounds more high pitch. an€d 1 more question do es anyone have a air sound coming from there a/c idle valve its the bolt with a spring going to a bunch of vacum lines hear it now but did not hear it before and all hose are on good
