If leaning the AFRs is how it allegedly makes power, and there is absolutely zero gain in that region, but gains where the AFR matches, is your claim still accurate?

Yes it is not accurate that way, you are right
But since i always (and not only me) have a bit of diffidence in dyno graph from producers, i would love to see if the afr still matches in a modified rom where the ltft is disabled on the open loop to see if it really consistently matches the afr or was just a "controlled" lucky run. Sorry
But i do appreciate the air straightener you put on your intake, that makes your intake the best aftermarket one I have ever seen... Good job
