car won't boost over 6 psi :(

i went and got my car tuned today ;D, but i had my boost at 5psi just because i didn't want to turn it up until i got tuned since my basemap was made for a smaller turbo. well we were doing our WOT runs and once we were done i went to tun up the boost. i have a homemade mbc and it usually worked before but now i can't get it to go over 6-7psi.

basically i have my mbc almost all the way closed and nothing changes.

my set-up is d16y8
.48/.60
greddy type S
CCA fmic
home made mbc

a friend of mine gave me a turboxs mbc to try but it looks kinda weird. just a long hose with a T at one end and a knob at the other. anybody know how to use it or what way it goes?

anybody have any suggestions on what could be keeping my boost low? im gonna try messing with the wastegate and boost controller in the morning.

sounds like one of those ebay mbc"s sounds like your the proud owner of a boost leak.

got it fixxed
i tightened the wastegate and everything is fine now. boosting 10 psi and feels great. guess my boost controller isn' ttoo great after all but it's sorta bleeding off boost right now like it's supposed to do so i'm happy ;D. i gott aget it retuned at WOT for 10psi now though :(
