It takes up to 4k rpm or so to get there, so I'm still scratching my head about that.
I figured I'd hit full boost much lower, perhaps as low as 2k rpm.
Maybe the Tbird guys will chime in here.

Taking until ~4k rpm to get 10psi indicates something isn't right. This would be fine for a GT3071R, but not the tiny T-bird IHI.
I suspect you have a leak, possibly at the WG. If so, you're losing a great deal of turbo efficiency.
