My turbo dont boost

Pressure test your intake system and remove all doubt. It shouldn't take this long to find a problem like this. Either you have a massive pre-turbo exhaust leak, or you have a massive boost leak. Check every single coupler. I don't care how new your intake setup is. Check the coupler between the 3000 pipe and throttlebody. Check the hotpipe off the bottom of the turbo. Check you intake manifold gaskets.
Hell, get the intake system smoked. There's a problem somewhere. If you hear the turbo screaming, stop boosting! You'll kill the turbo by over spinning it.
And I do NOT recommend removing the wastegate actuator pressure source. It's easy enough to check with a simple air compressor, not to mention that it's a LOT safer that way. (no risk of popping your motor)- the reason I say this is that we don't know all of your modifications. If you have something like an HKS FCD, and you pull the wastegate pressure line, you can kiss that motor goodbye after one good pull.

My lower IC pipe came off once, and I was blowing all sorts of black smoke, and the turbo would wail like a dying hyena.
Really sounds like a big boost leak.

To topic starter - you're using a ct-26 right? Is it a rebuilt one or the original turbo?
I'm by no means an expert but I would do two things...
1. Double check the Charge pipe and make sure it's connected properly.
2. Pull off the downpipe and look at the wastegate port. My original turbo had all kinds of cracks around the wastegate port from years of abuse. These could certainly cause you not to boost properly. You might want to un-bolt the wastegate actuator to get this done easily.
