Thanks. So what I'm seeing there is absolute boost requested peaking about about 12.5+14.7psi = 27.2psia. Odds are that your ambient pressure at the time was probably around 12psia, but could have been as low as 11.7psia or so. So probably the highest your requested boost could have been is 27.2-11.7 = 15.5psig. The rest was overboost.

Unfortunately timing corrections are normal at shifts (at least for my 6MT), but can be somewhat tuned around in the timing tables.
