Default Trying to Find Boost Leak

So I think I have a boost leak and I've spent a few days trying to figure out where it is. The first day I found one on the driver's side connection to the IC. But I'm still unable to build anymore then 2psi in the system when pumping air into the system. I was messing around alittle more today and found that the hose at the outlet of the turbo was leaking and I was able to get in from underneath and tighten that one down. Next I found a leak at the surge valve. Its leaking on the left side of the valve between the back bolt and the front bolt. You can actually see a visible gap on that side for some reason. I tried tightening it down with a wrench and it did close the gap a little bit, but not air tight. So there is still a little bit of a leak there. But even when I cover that with my finger, it still doesn't begin to build up anymore pressure on the guage, so there has to be ANOTHER leak somewhere else. This friggin car is a vacuum leak nightmare. And the worst part of it is that all the leaks seem to all be at the back of the motor by the turbo so its so hard to lean back there and listen for the leaks.
Just a pain in the ass and I had to vent. Any tips or tricks that anyone knows about would be great help.

Use liquid "Bubble leak detector" that is used to detect gas leaks. I found that the plastic intake was leaking using it. Remove the air box to turbo hose, and install tie wraps or clamps to all vacuum lines. If one small line pops off you will loose power.
