car studdering, turbo not spooling?

[TalonRacing07]

ok, guys i have a pte 50 trim turbo, with a 2g mas, 680 injectors, 255 pump, and everything else to go with it to support the turbo. also have fmic. rite now my vac is at 2--21 at idle. i go into 1st car will go up till 3k and then start to studder. on my boost gauge it won't even go into 1-2 pounds, it just cuts. could i have a really bad leak, or i was thinking it had to be sumtin with my bov or external. any help would be greatfull, i can't even spool the turbo rite now. it sucks.

I sometimes have the same problem, out of now where the car wont build boost and will have a hard time accelerating, If i turn it off then on again it goes away. It seems like a blown of intercooler pipe but i've checked all of them and they are fine. Im thinking that might be the bov sticking open.

hope you figure out your problem.
you should start with a boost leak test.
