I use propane or starting fluid to spray around vac hoses (at idle) and listen for rpms to pick up. this usually gives a good vicinity to start looking in.

either that on less dangerous get some soapy water and start spraying it round everywhere any boost leaks should start bubbling up

why do you think it has a boost leak?

Are you running stock boost or is it running boost control?

What kind of clamps aretpu using on the couplers?

i got a boost controller and set it around 15psi. 3rd gear at 7000rpm, im only getting 8 psi. tryed reseting the controller but no luck. could this problem might be a clogged cat or bad turbo wheel. i got a ct20b turbo.
