So I checked and under full accelerator position fuel state goes 47, I recorded it along with a number of other things, do you want me to send it to you??

that is not a derate, but a common code to see. Code 47 means that the engine mode fuel limiter is active for whatever engine mode it is running in. I.E.> it has reached its max allowed power for that particular engine mode.

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'
