Timing climbs the whole way so yes it's good. You can try taking out more fuel but by looking at your timing, i'm guesing you are using an afc or translator so keep in mind the more fuel you take out, the more timing you will get and the more likely you are to knock.
If you have a wideband, even better, lean her out and keep tabs on the timing. Definitely get the entire rpm range to at least 10.7-10.8 ish. You can go leaner before boost. 11.1 is about the leanest i would go to keep it safe but some cars wont let you run that lean so find the sweet spot of your car. It should be between 10.5 and 11.1.
Yeah, more boost is not a bad idea since it will put you on a higher airflow map and reduce timing slightly, thus reducing the chances of knock. Although it does take alot to make enough airflow to counteract the effects of the piggyback on timing.
Unless you are already running 20 - 22psi.
