Does anyone have the proper fuel injection interval numbers? Length of firing in milliseconds

I’m having a running rich issue with starboard motor. Yds shows twice as long injector opening as port.

On all 4 cylinders. Tops of pistons are black like the plugs. Which are new this year. Port side pistons are grayish with clean plugs

Swapped ecus and fuel pumps. No change on injector duration. 6ms on starboard. 3-3.5ms on port. Not sure how ecu decides this timing but must read something like a vehicle uses a maf sensor

I have a 2008 and had a Throttle Position Sensor go bad. It had an effect on the timing at idle. You may want to consider that.
