What would happen if you did the old disconnect the battery, hold the brake and make the car relearn? You know start it back up with the new setup. Let it idle for at least 30 minutes and then do some pulls.
Granted you would be looking at a possible change in ambient temps, and enviornment after too long, and therefore not being being able to replicate runs over and over. Not really being well versed in how these cars handle changes in setups this may not be how things work any more. Just curious if it might help?
I'm just going back to my old 2.2L accord days. So again please forgive my ignorance.

What you're describing here is exactly what we did, but with less of an idle time. The ECU did seem to correct a bit on the first run each time, but after that, things seemed pretty consistent. We have long and short term fuel trims for each pull as well that were still working through. We should definitely be able to paint as clear a picture as possible with all of the data that we collected. I'm working on charting the pulls we did with a couple aftermarket intakes for today, so we're getting close!
