i have a stock tmic and stock turbo with about 65,000 on it. my other buddy told me that it might be the turbo can't push that much anymore. but i am going to go home today and recheck all my hoses and fittings and make sure everything is really tight. then maybe i'll go and test it out. i'm also going to call ss later today when i get off work to see what he thinks. thanks for the help guys.
