Reality figures tho are much lower. City is killer.

But 6MPG is crazy low, Unless you stay in 1st everywhere you go and don't care about driving at 5500 rpms to work.
The OP states 6 mpg less than he used to be getting. Still not a very useful figure though.

Well how are the 605's burning? Do you have much KR? and so on.

If they're a little cold, then it will run and idle better with the 606's. Will be a touch more prone to KR, but I'd pulley up if that's the case.
