Yeah, but it's probably determined by referencing a load x RPM table, so it would still be ideal to edit the actual values in the table directly.
Although, I suppose they could spoof it by sending altered MAF/load readings, and then just adjust AFR and ignition to compensate, but that might create all sorts of weird driveability quirks.
