Track tuning issue, please reply and help

So i went to the track yesterday and logged a few logs. Can anyone please point out what's wrong with the timing? And for whoever has the ProfecB spec II, I had to turn the gain up to 49% to be able to get a peak boost 18.9psi, is this right? The boost does not hold steady, i saw the boost controller tried to adjust the boost level and the boost went up and down during the run. The end result is a 13.7sec pass with 98mph trap speed.
Please point out if I am running too lean or knock issue, and how to adjust the damn EBC!

Important mods are: 16G, 550cc, 225fuelpump, safcII high setting at around -19~-20, FMIC, boost set @ 19psi and dropped down to 16~17 at 7000rpm.

That log looks good actually. I would say get your boost problem figured out. I ran the time in my sig with basically the same mods as you but with 20psi.

I know I should run a little better than 13.7 but i just can't figure out what's wrong with the boost controller. Maybe SpecII just simply sux, i gotta go out and play around with it. For the O2, I know I shouldn't care so much about it but on other few logs, the o2 dipped down to .90 but the timing still increased. Do I simply ignore the low o2 value because my timing still looks good?

Basically yes, as long as your timing doesn't decrease then your good.
