how many mg/stroke and what engine mode is being applied when that code is showing?.

mg/stroke Can be monitored by watching 'Total_fueling'

and active engine mode can be seen via 'CBR_Chi_Table_Mask' and 'Chi_Mode_Status'.

turbo position can be seen at '_VGT_Actuator_Position'

I recorded a data log with most of that in but to be honest I don't know how to review it. I will Email the files to you.
