Default STi UTEC MAP. Feedback requested.

(Plus for what it is worth, a lightened flywheel.)
all mods listed here

The map is for running 20 psi on this setup and keeping the AFRs in the 10s under heavy loads to redline. Since posting this map I've advanced the timing some in the 60-90 range from 5500 up just a tad and it's still safe. With the help of the guru's at wrxhackers I've tried to keep the whole thing as safe as possible, and am now looking for areas to improve performance, but the chances of finding STis with similar setups is slimmer than finding similarly moddified WRXs. So I've come here to spread it out.

Any feedback is appreciated. The timing mostly needs help. It's safe in the trouble areas, but could use some gentle nudging to get more power out of it in the other areas.

I run lower timing in the spool up range, but a little less than you in the top of the rmp. Turbo is a sbr Gt-10.
