These docs from https://dis.epa.gov/otaqpub/ (which I have posted about in the past but not recently) often contain quite a bit of information, and are somewhat hard to decode and understand. As is often done, the (zero emissions) certification of newer models is based on the testing of previous model year vehicle hardware (carryover), sometimes with calibration updates.
Attached is the Application for Certification for the 2023 Mach E AWD extended range vehicle group which also covers the Ca Rt 1. 2023 test groups start with "P"; 2021 is "M" while 2022 is "N". In the attached document (see pdf page 34) note that the vehicle test group is PFMXV00.0B4A while the actual vehicle is "Original Test Group Name MFMXV00.0B4A" and "Original Test Vehicle Model Year 2021", and these are the test group and vehicle listed in the 2021 application. Besides the dynamometer test results (so unadjusted), which is why I look up these documents, there is also some info on 2023 calibration revisions - see pdf page 46;
ARC-341: Running change ARC-341 introduces the R09 calibrations. This
R09 release is to support an update to the ABS module to resolve a brake
NVH issue during Hold Apply in 23MY CX727.
ARC-347: Running change ARC-347 introduces the R10 calibrations. This
R10 release is to implement a BCCM update as a permanent corrective action
(PCA) for a melted charge port concern.
and then some details about many module revisions for ARC-341 on pages 50-52 (for EPA, then repeated for Ca ARB) and the ARC-347 on pages 56-58, much of which is not just charge port related (example, Thermal - Decreased max A/C compressor speed at lower ambient temperatures for better NVH.)
Someone with more knowledge and interest can probably relate this info to OTA updates.
There is also a table of module calibrations on pdf page 18.
There are similar documents for each of the Mach E models, but the ARC-341 and 347 parts are the same. Sorry, no particular new info on GT power limits, but maybe in the future when the calibration changes are actually released? There is some GT specific cal info, some probably related to power limits?
Also attached is the document that covers 2023 AWD standard range that includes some info on the LFP battery (PZ98-10B759- BD battery assembly, P so 2023) along with the original battery MNJ98-10B759-DF, M so 2021 (pdf page 15). The test vehicle for LFP is 2023 (see pdf pages 35-37 and pg 45). This doc also has an additional calibration section, ARC-361 which includes some interesting BECM changes along with other modules.
Compared to the original 2021 battery, the 2023 LFP vehicle and battery weigh more, has more useable energy, and a little more range.
Note that these documents are for emissions certification (zero in this case), and are often "worst case" for energy consumption and not always the basis for the data in the EPA test car list and then the adjustments used for the Label energy consumption and range.
