Wondering how a new MAF makes a difference? A friend that has a BRZ let me borrow his MAF. I took off mine and and put his on. Took it for a drive and still had the problem.
Was there something else that i missed doing? Disconnect the battery,etc?

your problem is a faulty lambda sensor, maybe you got it damaged , it swings between max and min so you need to replace that

Lamdba you mean o2 sensor? I did clean my MAF sensor with a spray for this kind. Still the same.

Thanks for taking a look. By what you see, those are the possible issues? What kind of steady state log would i need to validate your point?
Im thinking on doing another normal run and another hard pull and upload to datazap again (longer drives)
I would need something to show the mechanics to they can address the issue, from fuel pump problem to a sensor. They tell me its hard to tell without a check engine light.
