Boost leak on the turbo

LafitteZ

Well I just purchased a twin turbo g37 and I put it on the dyno and noticed its taking forever to spool it up. Well I put my boost leak testers on it to check to see if mabe there is a leak and then I notice I cant get the psi meter to even move. Im guessing its one of the couplers on the turbos because i checked 99 percent of the couplers I can get my hands on and there are no leaks. I can hear one tho and it sounds like its coming from the driverside turbo. Its not a gtm kit but the piping is ran pretty much exactly like it. I was wondering if anyone had an idea of how I can access this turbo without pulling the motor to check the couplers? I know some of the guys on here did the turbo install without pulling the motor just wondering if you could give me some insight on how i may accomplish this.
