I think you have just run into the perfect storm...Your mods + the change to winter fuels combined will have a significant impact on mileage. When the summer blended fuel comes back, it will get better. But that's only part of the problem. You need to tune that HEMI and give it some more air.

You can help things a bit with a cold air intake and an exhaust. Consider getting a programmer as well to optimize the engine operating parameters.
