Honestly it's figured out at this point, I just need to draw the pretty pictures. I want to leave the ability to use the stock harness with the stock plugs intact. Just off to the side while the sensor we need is in place doing it's job.

When the 32 ECU was in and the car was idling, A/F was on the money. Tad rich, but damn good anyway. The issue is that the car would only start the one time with that ECU in. Come to find out it was a stupid sensor that we even had! Oh well, it'll be up and working good soon. Then it will be a matter of how much boost can we crank without needing a tune.
