Actually, target boost @ 1200 rpm for a 3 liter engine isn't all that amazing.
The larger the displacement, the smaller the turbo it needs to make the same power.
So it is unlikely to be as large as a turbo on a STI (2.5L) or evo (2.0L).
Add to that the fact that a 3.0L is blowing more exhaust gas (pre-spool).
Basically, 1200 rpm on a 3L is like 1800 rpm on a 2L. (And the 3L is spinning a smaller turbo.)
So yah, not surprised that it would manage full spool at 1200.
1) turbo is smaller (than an EVO or STI turbo, which use a big turbo to make up for a smaller engine)
+
2) you have more exhaust gas (pre-spool) to get it spooled (since you have more liters than an EVO or STI, you can make more exhaust off-boost, so you can put more force on the turbo to get it spinning.)
=
3) Max torque at low rpm.
I don't expect it to be laggy either. But, they don't mention now long it takes to reach full spool when doing it at 1200 rpm.
You may find that you can hit your target @ 1200 rpm, but it will take 1 second longer than it takes at 3000 rpm, etc. (this is a 'duh' statement, but whatever.).
