heres my problem... i was in 2nd gear and took it to about 6500 n heard a pop noise about 15lbs of boost... car is driving like a normal non turbo car vacume is reading its normal readings like it use to before... i took apart the waste gate and it seems to be fine any ideas of what else i should do... D16y7 engine

 

you probably blew a coupler off, double check your turbo piping. its common to blow a hole in one or break a clamp and pop a coupler off,
