I have noticed it in my 2018 manual sometimes, but when it happens seems to vary.
I don't apply full throttle to notice it, just progressive wider throttle and can feel flat sometimes, but not all the time. I wondered if it does this when the engine is quite new and less than a certain mileage.
If the part number for the bezel/panel is JR3Z-63044D70-BA would the part number for a RHD Australian/NZ Mustang be just a simple difference to the last part of the part number, the "BA" would be something close?
I have tried various combos on fordparts but cant find it, also our export VINs...
