Default Running on 3 cylinders..

So my problem went from bad to worse. I sent out the 650's to be tested and cleaned and they came out perfect, even before cleaning they were good. At the moment the car is running on 3 cylinders..now let me explain how we got to this...

I tested all the injector clips for voltage, 11.55 all across the board, next i tested the coil packs for power balance and this is where i saw issues. Cylinder 3,5,6 do not have any effect, on or off. However when i turn cyl 3 off the car idles up a little and then back to stumbling on its face. I have swapped coil packs between 2 and 6 and has no effects, still not working. I have cycled through the power balance phase multiple times hoping it was a blip, no luck. I also did a compression test and i was 220 all across the board...the air/fuel is pinned lean (20) on bank 1 and sits about 16 on bank 2..FPR is pegged at 53 off vac and 44ish on vac..any ideas?

FI TT Kit, car was running fine until I installed the ID1300's and it had a slight skip at idle so I returned them. Put the 650's back after being cleaned and tested and now my car went from skipping to full blown retard mode...

I'd check injector wiring.

I'd Check for a bad connection on the main harness,for whichever bank isn't firing.

I ordered a new injector harness, I am going to run jumper harnesses this time around. Maybe when I disconnected the coolant lines running to the TB it got inside the connectors and corroded them..who knows

Resolved...re-pinned the injector harness, probably bent a couple throughout the 12 times I took it apart.

Yeah man just need to find a small leak somewhere in the wastegate vacuum mess..it seems to be a little unstable and inconsistent with boost pressure.
