It's too rich at full throttle. Anywhere from 10.2 to 10.8 commanded. Without a wideband I don't know how accurate that is to the actual AFR the wideband would show. We can't see custom channels you create using the EGR if that is your method of logging.
That could explain the high injector duty cycle. Cutting back to 11.0-11.5 could cut 10% from the IDC. Though I do forget if the IDC is accurate on the 2004+ computers, something in the back of mind says to me that that was a topic long ago but I can't put my finger on it.
I'd like some clarification on what the commanded to actual AFR is like. You should not have a large error between the two.
The part throttle knock isn't something I could give you a good guess at. Certain harmonics or a weird vibration maybe.
