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.

In for updates, hope you get it figured out.

I'd Check for a bad connection on the main harness,for whichever bank isn't firing.http://uploads.tapatalk-cdn.com/2016...bf5f96e97d.jpg

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.
