Here is a little update...
Its now 4 months of running blufin
After 3 months I called them to advise that the fuel consumption was getting worse and not better, at the start I knew this would reduce due to the extra power and and my right foot wanting to use it all the time

.
So they sent me a new map(same day i enquired), waited a couple of days after installing booted the arS* out of her felt just as quick, so settled down to normal driving again with the odd rash moment and hy what a difference, I know its the oil burner, now on a daily average I'm over 50 mpg on the same run where I was getting about 45 mpg. Don't know what they did but it has sure made a difference.
Sorry still no rolling road all my spare cash is tied up in this years holidays at the moment...
PS no issues with the car at all with this installed..
£400 well spent? don't know if I would do it again, would probably get the better BHP engine to start with
