My V10 E350 gets 12 city and 14 highway normal driving, 13.5 city and 16 highway with gentle driving.
I don't know if you tow much but I run a K&N air filter that gets me better MPGs towing, but its the same empty.
You might want to try slightly firmer shifts, but any change will be very small.

If you got the Hypertech in the last month or two I would call them and try to get a refund based on the fact that you are unhappy with it.
Its at least worth a try.
