So after a few weeks of the issue being much less noticeable and my thinking this is a result of the adaptive tables provided by MHD, the car has gone back to its much poorer upshifting, power delivery state. No codes still and same fuel.
The only thing I have noted and I've noted this before but not consistently, is that the car has low fuel (50 mile warning came up in last couple of days).
LPFP? (HPFP again?)
