This is horrible I didnt think It was this bad. Fuel system wise what do I need? The system is stock right now besides a rewire. I have 550s waiting but I did not want to put them in and f everything up if its even possible.

you need to turn the boost down until you put in... injectors, fuel control, fuel pump.
550cc (you have)
walbro 190
AFC or DSMLink, you could probably even get a way with using a GM MAF and MAFT to control fuel but since your MAF is fine i'd just say AFC.

If money is an issue I'd turn boost down, put fuel pump in and go from there.
Hope that helps

since you're getting a constant o2 voltage at WOT, I would say that you're RUNNING REDICULOUSLY LEAN.

you're getting a shitload of knock throughout your entire powerband.

If I were you, I'd either turn the boost down or put in your fuel and retune

ok for the life of your eninge you NEED TO turn down the boost for now. alot. Buy a walbro 255 lph FP, an Aeromotive AFPR at 42psi, get your inejctors, and choose your path of tuning? MAFT Trans, SAFC, SAFC&Maft Trans, DSMLink? then retune with current boost.
