Great thread and great info! Kudos to stup for doing the tests and explaining the procedure!

Now to throw the spanner in the machinery:

OEM pancake intake is badly made and flows unevenly to cylinders. The very final touch would be to take off the air-injector plug and connect a copper-tube leading to WBO2 sensor (WBO2 needs very small gas flow to be accurate).

Then you could fine-adjust injector flow to each cylinder to same AFR. Middle cylinders will generally have higher AFR's than others. Also, you could add a tad more fuel to cylinders 1,2 in order to compensate for worse cooling they recieve
Thank you for your time,
