Has anyone noticed any differences in their Prius after the software recall/update? I've been keeping gas mileage records since I bought my '05 in January, and it seems like the gas mileage is slightly lower now, and I don't get as many miles to a tank of gas.

Unfortunately the cold weather here in Ohio started at the time I had the upgrade, so I may have to wait until next summer to get a good comparison to my previous data. Cars generally get worse gas mileage in cold weather and I don't have a complete set of data from winter '05

I'm wondering if Toyota discovered that the major problem with the stalling incidents was people running out of gas, and maybe they reprogrammed the gas gauge to save more in reserve.....? Maybe I'm just being too suspicious? Maybe they're out to get me.....??!!!

Any other ideas?
