205 tyres are wider than 185!
My driving is pretty similar to yours in terms of being 60% motorway and im averaging 45mpg over 3500miles http://www.spritmonitor.de/en/detail/583387.html
A stage 1 map will increase your power but will also increase your economy.
A straight through back box, de cat and EGR blank (blank it properly in case its leaking) will also help.
The real best way of improving economy is narrower tyres. Swapping from 185 wide to 205 wide saw about a 20% drop in my MPG on the scan guage.
If you want to go really extreme stripping the interior out the car can give 5-10% better MPG
