Cafd files only provide values or decisions to ECU firmware. SIB upgrade updates the ECU firmware itself, thus upgrade may have same or different set of values.
Throttle lag was updated by Varying the torque-speed characteristics. I'm sure it is implemented thru series of data points but not sure where that data reside.
