You'll have to figure that out yourself.
Get yourself a wideband o2 sensor so you can monitor the real time air fuel ratio's.
For now you can hook up a fuel pressure gauge to the fuel rail to watch your pressure. Add more channels to your logs too. Like commanded AFR, knock retard, injector pulse width avg, cylinder airmass, a wideband o2 sensor.

If you don't post your tune and logs when you have questions you aren't helping yourself.
O2s have nothing to do with fueling at WOT. If your adding fuel and its bot getting more rich your most likely not getting the fuel.you need.
