Do I need a large compressor to test for a boost leak?
I am currently using a small 12v compressor and inputting air at the turbo intake-I isolated from turbo inlet to throttle body and that held at least 20psi from my small compressor. Now I have the system hooked up as normal (just that i'm pumping air into the turbo inlet) and it won't build up any pressure...before I was detecting a leak at the injector heat insulators and replaced those-they make no noise now...is there somewhere else the air could be escaping not allowing it to build up pressure-OR do I need to pump WAY more air into the system to find leaks? Thanks!

have you tried rotating the motor. I remember one time with my old boosted car, that the motor had stop just at the point that both the intake and exhaust valve were open on one cylinder.

You pump the air straight into the turbo inlet. There's no point doing it at a point before that as tubing prior to that is not subject to >atmospheric pressure. Plus, a 'leak' pre-turbo wouldn't matter if you have removed the AFM... actually you wouldn't even call that a leak. Stop going mad trying to find an uber strong compressor - my bicycle pump can push 100 psi into a road cycling tire and can inflate my race tires... ANY compressor is more than enough.
