i'm with no means a tuner, i just tell u what i see.

ive put all those logs in tunezilla and here are some things ive noticed (which u already did too)

Log 1: Bit weird that your maxed out on stft.
Log 2: can't find anything
Log 3: also can't find anything
Log 4: your WOT run, MAF reads good (as expected), and stft goes rich (because your ltft is probably high lean), just like mine did.
Log 5: Boost log, also seems good, maybe even better than mine

I can only say, check your basic things, pcv. leaks, etc. but ive read u already checked those.

Isn't there an option for u to stick a standard ecu file in it and see what is does? Maybe a fuel delivery issue?
