hmmmmm, my EC v7 with catless headers made 472/435
did you only do one pull on the v6 flash then flash right over to v7 and do only one pull?
did a few pulls, those were the best for both software versions. But yeah, flashed v7 then did a few pulls so that may have affected it a little since it didn’t have time to adjust.
I really want to know more about this whole 'learning' thing. I was always under the impression that it was learning AFR/fuel trims, which would result in a nominal improvement in power and drivability. What else can the ECU possibly learn to make better power

Hi IATs ECU pulls timing cold IATs adds timing
Fuel Octane high Octane EcU adds timing low Octane pulls timing

Fuel Octane high Octane EcU adds timing low Octane pulls timing
And all viceversa for fuel trims and AFR
also ECU learns driving style and gearbox modes
All true and i hear you on those points....
However...if say, IATs are favourable (in he 20c range), fuel being used is good and target timing of say 25 degree's is being achieved (on the dyno after a tune has been uploaded)...what else happens after that with the learning?
I can understand if the ECU by default refuses to hit the target numbers due to safety and wants to slowly ease itself into it while monitoring knock, but I can't understand it if all target values have been achieved in the first place. I'm saying this largely because on my car it has very recently decided to give me a bit more pull and smoothness in the power delivery since when I dyno tuned it. Fuelling and timing is the same as what it was before...
Strong numbers for Arizona, but it's hard to visualize without having both on the same dyno chart. Anyway you can have dyno-comp put V7 vs custom tune on the same chart?

Maybe you have some secrets your not telling us
TBH man i really cant answer answer of your learning questions i can only pass on what experiences i have with the process
Best person to answer these questions would be the Tech guys from Weistec
I would love for Anthony to come on here and explain
