Mine's a factory manual and had the same hesitation with the stock fuel mapping. With the S-AFC tuned and cutting 5-15% fuel between 4000 and 8000 rpm, I can go WOT without any resistance and response is instantaneous. May be related to factory ECU tuning to 100 RON fuel in Japan and factory map overfuelling to avoid knock and to keep valve temps down.
