From when I parked last night until I went to start it this morning the car sat for 12 hours in the garage, doors locked.

I unlock the car as I'm walking up to it and I also don't start the car until the system is primed. The car has always primed itself upon unlocking the doors which is by design. This is the behavior stock or with the tune. This recent behavior is new and never happened before.

Sure, there are lots of other factors to consider with a slightly longer start and a slightly rough idle but that still doesn't explain why the LPFP is no longer priming the system.
