MY car is stock when it comes to fuel mods. So what would be a safe setting for my new MBC? I was thinking around 14psi.

You can't really tune with the stock narrowband O2 reading. What values are lean and rich at WOT vary from car to car. That said, 0.90 is a pretty common O2 value at WOT. You're probably running right where you should be.

As far as your fuel trims go, as long as they are not maxxed in one direction or another, you're fine because the ECU can make the necessary amount of correction. 120 is max, so your fuel trims are fine.
