My car fluctuates about .10 gallons per hour. I figure recording the high and low and then averaging should tell me whether it improved at all.
Aim a camera at the ultragauge, and count the seconds it spends at whatever value, then time-average these values.

The mods you plan to do have previously been done by others, and they have reduced their fuel consumption by doing so.

Taking accessory loads away from the engine, improves FE.
