Default 2010 WRX datalog. advice please!

so I got my AP thursday. been playing around with it. did one other log and wasn't hitting my boost targets so went to the hwg stage 1 91 octane map. i'm in alaska so running 90 octane. the only thing i've done to the map is increase the boost targets at 1600 and 2000 rpm by ~0.5 and ~1psi respectively at 240n*m req torque and above. No knock or anything but my inj duty cycle is showing over 100% at 5900+rpm. Am I reading this wrong or do i need to back the boost down? thanks in advance.

Can you log boost error and target boost?

Regardless you'll probably want to change the boost targets back to stock levels. The 90 octane we have up here isn't really up to par. Most people have to retard their timing slightly to compensate.

You're A/F learning trims in closed loop are pretty large. It's possible you could have a leak somewhere that would cause your trims to be off and cause you not to hit target boost.
