Stock O2 sensors are not accurate enough for WOT tuning. Go by Knock, keep it around 10 counts. you want timing to be around 20, but higher is better with the 14B, as long as your engine can handle it.
Get a fuel pump and rewire it ASAP. then you will be able to run that boost safely.

this isn't always true.
I've seen cars grenade at 3 counts of knock, you just have to know the difference between pinging and 'artifical knock'. Also just 'tuning' by knock isn't important, its nice to look at intake temps, injector duty cycles, o2 voltage, egt readings, a/f ratio, coolent temps, etc... all play a factor in a well tuned car, but since he has nothing to tune with, we won't go any further.
Anywho,
most dsm's are safe to run up to 10 counts of knock, due to the fact that all the 'noise' they make, but in his case he is actually detonating from running lean. Please refrain from using blanket statements when it comes to tuning cars, it angers me.
Now alpine, here is what you need to do.
1) fix the boost creep, get it to a more manageable 14-15psi.
2) check for boost leaks, before and after turbo (unmetered air like mike suggested).
That'll get you by relatively cheap.
3) Obtain some form of fuel management, just because you are running '510cc's', since you are on the stock 1g fp which runs 36psi (your injectors are probably rated at 43psi), they are actually smaller than that. Look into a fuel pump, or at least check the voltgage at your fuel pump. Next look into getting some sort of fuel controller, choose your poison. (I prefer s-afc, its plug and play, and fairly easy to learn the basics about).
from there it can go any-which-way, pending if you want reliability or speed, keep us posted.
