Man, I thought I was the long-winded one! J/K

The Mirage has a Linear AF sensor in the exhaust manifold, I've been able to read a real time AFR from it, do you think it'd be safe to use that instead of having a separate gauge installed? Since it's already there and all...
Also speaking of duty cycle, from the other thread about the injectors Daox had them flowtested and got 230cc, which according to some math says the fuel system can handle 130hp at 100%. Using an app I found that at WOT the most it ever went was about ~60%, so it sounds like the Mirage isn't taking full advantage of the injectors (makes sense for a conservative OEM tune). It sounds like there's plenty of room for improvement here, but I wonder if you cram the Nitrous down the intake will the ECU actually add fuel to it or just go lean?
I hope I don't sound like I'm discrediting everything you just typed, I feel like there's multiple threads happening about different parts of adding performance to the Mirage (this thread, injector flowrate, ecu tuning/piggyback).
Edit: Best I could do for Injector usage was 13.8ms @ 6500RPM, which is like 75% duty cycle.
