Hi Roger
Yes, stock engine bar the ecu. My 'commuting' is rarely during 08-09 or 17-18.00 periods but it compares to approx 45 mpg previously !
Ref 3rd and 4th, less noticeable as I have always used 3rd as gear of choice for overtaking but Chunky reports an *unprintable* speed achieved in 3rd

4th again has more oomph at both ends of rev range, so bassically I'm changing gear less.
Cheers
Jeremy
