Default LQ4 Tuning/Timing opinions wanted

I took my car out a couple of weeks ago and was pretty impressed with it. I managed to go 11.5x @ 119 mph with a sorry azz 1.8x 60" on just 7psi. I did this with only 15 degrees of timing.

My goal is to break into the 10s with about 12psi of boost. I'm thinking about bumping the timing up to 17 degrees. I will also be spraying meth this time starting at about 10psi even though my IAT never went past 136. So my questions are below. Thanks in advance!

1. Is 17 degrees too much timing?

2. Would you guys rely more on just adding boost to get my times or tweaking the tune?

3. Is there a way to adjust timing according MAP?

If you just want 10's you can leave the timing alone, 12 psi will get you there

If your tune has a targeted AFR for boost turn it up and let it eat if your confident your fuel system can keep up.
