So you've synced nds with the timing light on the crank? If you are plus or minus on the crank nds is wrong. You have to know this for certain.

Try idling with the mafs disconnected record a log for me.

If you have an adjustable fpr, disconnect the vacuum line and plug it. Base fuel pressure is 43.5psi or 3bar
Raise the fuel pressure a few psi clear self learn and log
See if it goes richer or leans out and how long it takes before a change is notice. Then try a few psi lower. If there's no significant change put it back to 3bar.
