Default Day to day MPG fluctuation

After replacing the EGR valve I had EXCEPTIONAL gas mileage and I thought I'd found my problem. but the next day it was struggling again. I'm in Houston with no hills but some days I just can't maintain 60 at a reasonable MPG while on GOOD days I seem to cruse along at 80+mpg happily.

Nearly new battery.
EGR valve is new
EGR plate is clean.
180k miles

I've even seen MPG fluctuate while driving steadily (not a regen)

I'm thinking TPS or MAP sensor.

Anyone else experienced something similar?
