Has it always been 20-21psi, or did this happen after certain mods?

Turbo Vanes could be stuck and needing a cleaning.

It could, your gonna need to mix up a soap/water solution, spray it on crack, have someone throttle it to see if the soap/water solution bubbles. You also need to check the up-pipe/y-pipe flex joints for soot deposits which would be a crack in them pipes. Take a good look at the IC boots, especially the one coming off the turbo, sometimes the rip is noticeable, sometimes they rip just under the clamp where you can't see the rip.

I had cracked one of my ports for water/meth on my CFM+ elbow, used a poxy like JB weld to fix the cracked plastic around the brass insert.

i know my exhaust isn't cracked cause i just had my turbo off to do the stc upgrade and checked it. now it may be my IC boot on the turbo, its been on and off quite a few times ( i will check it.) i have been thinkin bout replacing my intake elbow anyway... lookin at the s&b it has the ports and high flow rate.

Just because you checked it, doesn't mean that it couldn't have just happened, reinstalling a turbo and aligning the exhaust pipes take a toll on the flex joints.

The only thing your gaining on a aftermarket elbow is the tapped ports, your not gaining any more air/flow, the main restriction is the intake manifold and ports of the heads. You might as well stick with a stock elbow, unless you like wasting money and want a fancy one.
