I made sure everything is on correctly and tight

So I had a bad 12a turbo it was seized when I got it I put a rebuild in it (new bearings, seals etc.) I have a 1g bov hooked up to it and a cheap Manuel boost controller along with aftermarket gauge I was running 11psi of boost it worked and ran fantastic pulled hard was doing great then last night (3 days after I rebuilt it) I was racing around and did a burnout I saw my gauge during the burnout it was 9psi then got down to the next stop sign and then started going and my car wouldn't boost it got to -1psi and made a weird deep turbo noise and was like "wowowow" like a howling woosh I thought great I just fried my turbo I drive it home easy and tore into my turbo got the insides out it looked fine the turbine spins free sounds fine feels fine and has a tiny bit of side to side play but it was like that when I rebuilt it to I checked my intake and exhaust housing they looked fine I put it back together took it down the road and it did the same thing I'm lost now what do I do?!!!!

So I just got a 89 conquest and it was in a small front end accident I bought it from a friend and when I got it there was no hood or radiator and it had the intercooler and piping but it wasn't hooked up we put a battery in it and started it it starts right up idles fine but won't rev up good and it has some black smoke out the exhaust so we figured to much fuel the turbo wasn't hooked up so it wasn't getting enough air so we piped in the turbo (NOT PROPERLY) and it still ran bad the engine needs a tune up but it's not so bad that it would make it run bad
