HELP!!! Options

[resalturbo]

i was driving along tonight and i got on it in third at about 3000 rpm's and decided it wasnt enough pick-up so i downshifted into second and layed into it then i heard a squelching noise so i let off and gimped her to the closest spot with a street light

i get out and check all of the intercooler lines-intake-blow off lines-
and they all seem to be tight
so i get back in and take off and now if i go over 5psi i hear a loud whistling noise and i gets louder as the boost goes up, so i gimp it to where i am almost home and i get on it to see if there is any perfermance loss and i didnt feel any loss, but the whistle now starts at 3psi, so i at home now and am at a loss for what i could have done

did i just blow off an ic pipe and dont know it??
could there be a hole in the intake??
did i **** up the turbo/wastegate?
or could it be just a minor boost leak somewhere??

i am at a total loss and dont want to hurt her any more if i am at all.
let me know what you guys think
thanks in advance

well i pulled off all the intake pipes and ic pipes and they all seemed to be ok and while i was in there i spun the turbo to see if there was any shaft play and there was none whatsoever so i dont think it is the original turbo cause the car has 130xxx miles on it

anyway back to the problem at hand put it all back togethere and the noise is still there, looked at the boost guage and pulled it out and traced the lines and they go by the door jam down to the floorboard and out the firewall, so maybe opening and closing the doot just wore it out, but they seemed to be fine so i am going to stop and grab some hose and rerun that line to see what the hell is the problem,
what size line should i get???
the whistling comes alive right after i hit boost at about 3-5psi
thanks for the help guys i appreciate it
