returning the ecu back to stock did not make any change, so it has got to be one of the mods that is causing the issue.. air filter perhaps?

For my car instead of increasing the trim, I decreased it, and now the car sits very close to what is in the target A/F table without touching the compensation table. it is not perfect, but pretty close. the car used to see like 10.5:1 where the table was set to 12:1 for example. I am guessing that Nissan did it this way to leave the head room for low octane fuel for safety? purposefully setting the car to run rich so it wont cause damage.
