I didn't say that......I just said I have seen somewhere between .6 an 1.0 difference between the port and collector o2. Every combo is different. The OP just asked if the variation between the two is common. My answer is yes, it is common. But from what I've seen, once you get all 4 holes in the bank balanced out nice, the collector number starts to come around, as well, like you have found

The sequential EFI stuff is really neat to fine tune the individual holes. I have really enjoyed messing with that, sounds like you have, too!
