Requested load is used as an axis in the requested TPS lookup (DBW tables) which is used by the BCSDC Base lookup.

Gears with less requested load will potentially have lower requested DBW throttle, and then lower BCS DC base than gears with higher requested load.

Another case of over thinking :)

Because usually requested load does not differ much per different gears. WGDC table is just a "base" table, the actual wgdc is afterwards adjusted depending on what load was reached. In higher gears there is usually quite much time for ECU to adjust to it accurutely, so I would try to match wgdc to your lower gears (or highest load, whichever you prefer)

+1, I also set the wgdc between 5-10 from what is required then use higher values in the correction table. Helps prevent overboost and oscillation.
