You need to pressure test your system... Tap or weld an 1/8 bung and go get a plumbers cap that fits the inlet of your turbo and then hook up compressed air to the tap or bung and boom you will hear it. If you can't you can also spray soapy water on all the connections

OK so i made that boost test tool today used it and the only leak i found is a pin hole in the intake tube for the turbo its an aftermarket bigger tube and it looks like its coming from a weld and its right next to the turbo housing. would this tiny hole be causing my 5 pound boost leak?
