Indeed, I finally figured it all. I removed the fix, which indeed wasn't one, and finally figured out why the value aren't the same. It's because... they aren't the same. Acurite report Pressure, Weewx reports Barometer. All that was required was to change the template to display the Pressure($current.pressure and $trend.pressure)
I felt stupid :P But hey, I learned alot about weewx in the process! Thanks!
