What it does
Provides MAF scaling for the larger MAF housing used with the ETS turbo kit on the 2022+ WRX. It addresses the housing change rather than supplying a complete turbo-kit calibration.
File and hardware
The August 27 attachment was prepared for a G30-770 customer setup. The author explains that the housing-related scaling applies across kits sharing that same MAF housing. Confirm that your actual housing and kit revision match before adopting it.
What still needs tuning
Compressor and turbine differences still require VE and calibration work. Do not treat the attached table as a complete ready-to-flash tune or as proof that fueling, load, ignition and boost settings suit another setup. No later file was present in the reviewed discussion.
