Mobil One didn't do a thing for my mileage (I'll still use it though).

Well after the lesson we got from 07 he still hasn't given you a concrete answer to why you are INDEED getting better mileage.
It was not an illusion. You increased the volumetric efficiency of the engine.
With the denser intake charge, and static ignition timing from the ecu stock program you will be able to increase your mileage slightly. It is slight but it is still an increase. In some cases you can get a few more MPG, but some don't ever see it. Due to the fact that they most likely see WOT more often now after modding the car.
Anyway, figured you might want someone to back up your theory.
