When you reset the error codes it also resets the trim values. Takes a few miles to calculate the trim. That’s probably why it’s zero.
Could be you’ve got a turbo that’s not boosting. The other turbo pushes air back up through the other MAF which is why it reads zero, or funny values.
Boost - 12 years in and it’s still a ball ache
