I do lots of short trips in the family hauler G37, so the effect OP described feel very pronounced to me when I do longer trips, especially in warmer days.

Regarding throttle response...on stock tune, it almost feels like the throttle body is opening up even slower when fully warmed up and heat soaked, it’s a much more sluggish feeling vs that of a cooled engine. I think this greatly compounds the feeling of losing power.

Not saying there’s nothing wrong, just the stock delayed throttle response doesn’t help at all.
