You have the injector dead time set incorrectly.

Post the calibration.

System voltage is normal?

this is the calibration on there now

You should also post a datalog of the problem as it's happening.

i cleaned my grounds and its been acting a lot better but heres the data log i had saved when it was happening you will notice the lean happening is when i put the lights on and when it goes back to normal i had shut the lights.

Multiple problems.

Your charging system is not good. The voltage should not dip to under 12V just putting the lights on.

The lambda seems incredibly rich even with the lights off; under 12:1 at idle.

IAT is high (125F). This will tend to make things rich anyhow. Do you have a hot air intake?

Why no closed loop?

im going to take a look into everything this weekend
thank you so much for all the input.
