Yup, that looks fine.

The table properties are undefined, so I haven't a clue whether it's timing added or subtracted from the total. I suspect it could also just be bad petrol, but that's another step to try later. |
That table looks like the retard applied when clutch is depressed. Best bet is to look at load limits, fueling and adjust the timing tables for the load if required. Boosting at low RPM is always going to be a little knock prone.
