Thats about normal this time of year. If you had some bigger injectors that would help and custom tunes.

Very well could. Have you read through the stickies and have access to a very good diagnostic tool similar to AutoEnginuity?

It could just be the fuel you're using. I was experiencing horrible mileage until someone asked about my fuel. Second tank on better fuel (less bioblend), and my mileage is steadily getting back to where it was.
