If you used the old lines did you carefully check each line for holes. I had a small hole near the passenger side wastegate that caused that wastegate to remain closed. It was tiny but I imagine with 23+ psi it expanded enough to cause a ruckus. You're past the hard stuff this is just where it get's tedius and irritating because now you just want to spool.
