Boost problem?

[clipse-T]

Ok i just got my car back from the body shop, the car was fine before i took it there. But now it runs weird, when i start to boost..the car stalls around 3-3.5rpms and will not pull or boost anymore, making me shift to go further..its funny because it makes a weird noise when it does this, i hear like an air whistling sound. Like i said it didnt run like this before but now i got it back and it runs like this. I inspected all the couplers/clamps in my ic piping..and there's a clamp missing from the uicp to the smic..i think i might have a boost leak there. Also i inspected the turbo oil feed line and it is crushed..so that needs to be replaced. Could this be a boost leak? or an effect of a crushed oil feed line that needs to be replaced? Any help is appreciated..please help!

boost leak. 3000rpm is right about where you would have that kind of problem, just when boost starts to build enough to upset the loose coupler. clamp it and you'll be golden.
