If you dont want to use the old, fairly dangerous carb cleaner method, I believe Wurth makes a spray that is non flammable that can be used to find vacuum leaks. It will cause the idle to drop if ingested into a vacuum leak. Ive also found that for turbo cars in general building a boost leak tester is a great way to check for both vacuum and boost leaks. Get a PVC cap, drill a hole and install a rubber tire valve stem. Then take a piece of rubber hose and clamp this to the inlet of your turbo. You can then pressurize the system with a compressor and listen for leaks without the engine running. Its also good for finding those pesky boost leaks that only open up under pressure.

get a vacuum guage first. Than propane or water works.

Old school:
A piece of vac hose held to you ear.
Probe the other end around like a stethoscope.

You can also pressurize the whole intake with some low pressure compressed air ... Disconnect AFM, put an adapter home depot style to the intake duct and connect your hose ... The leaks will hiss ... There was a thread some time ago that showed the contraption.

Remember that vac leaks do not always come from vac hose, they may come from diaphragms (ACV, etc).
