Good points. I can easily test the intercooler drop by swapping my plx gauge to a T off the boost controller while leaving the Holley MAP sensor on the manifold line. The two read within a half psi of each other, so it will be a relatively accurate test.
The Tial gate came with the turbo kit when I bought it used. My luck with used parts has been less than stellar, so it would be my luck that something is wrong with the gate.
For the spring, I've learned that having too small of a spring can prevent the turbo from spooling adequately to higher boost levels depending on backpressure. I'll up it to a 15 psi spring and see how that helps also.
