Do you really get a cylinder to cylinder or bank to bank difference in AFR with a port injected EFI motor?

It would seem that each injector, with the same BPW, off the same sized/length runner would have a nearly identical AFR.

I can see that with a carb or TBI setup or just spraying fuel into a large plenum but not with port injection.

To be clear, you're saying stock or near stock with iron heads 11.0-11.2 at WOT?

Interesting conversation, so on my 502mpi with aluminum heads and a side mount whipple at 6lbs of boost, my wide band says 10.5 WOT. From what is being stated I am to rich. Should I put the next size smaller pulley on and check it then to lean it out some to try and get to 11.6 - 11.8 AFR? Or try to lower the fuel pressure to lean it some?

Has anyone put a wide band on a bone stock set up of say a 502 efi? What were the numbers?
