Well when I first got my car, I wanted to make sure that all the boost (stock boost) was getting to the engine, and none getting wasted or lost through bad connections. So a friend showed me his boost leak tester. Basically what you do is take off the cone filter (works really well when you have a cone or pod filter adapter, or any 3" tube before or as soon as possible after the turbo) and then you put this thing on, tighten the clamp and pressurize the system to your desired level of boost. (1 bar, 20 psi, whatever you are going to be running). Then you listen for leaks.
Here's how its made. Credit to some DSM guy somewhere in the states.
Parts Needed:
To assemble, just put everything together as shown.
To get the valve stem in, I had to drill a hole in the PVC cap.
To use it, just remove the intake pipe from your turbocharger inlet, and attach this in its' place.
Now you need to hook something up to the valve stem to pressurize the intake so you can listen for leaks. I use a 7 gallon air tank I got from Walmart, I just fill it up with air at the local gas station. You can also use a simple bike pump.
If you have a manual boost controller hooked up, you might want to plug off its' intake hose, as they leak a lot of air, making it hard to pinpoint the real leak.
Pressurize the system, and listen all over for leaks. Make sure you or a friend listens under the bumper too, wherever there is IC piping.
A leak will be obvious, they make a loud hissing sound.
You might want to have a friend check out your boost gauge while you are pressurizing things, to make sure you don't put too much pressure on things. (20 psi should be safe, or whatever you run safely for boost).

Parts Needed:
- A 4 inch long piece of 2.5" O.D. (outside diameter) hose. (I used some radiator hose I got at NAPA)
- 1.5" I.D. (inside diameter) PVC end cap.
- 2 band clamps that will fit around the 2.5" pipe above.
- A valve stem (I used the rubber type you press in)
