Thanks for the information; I'll have a think. I'm seriously thinking about changing it due to the poor mpg, a remap would be MUCH cheaper, but not as effective as the latest diesel engines in a lighter car.

I'll have a ponder now that I have a cheaper alternative option as it might just buy me some time .

Having just re-read my post I wanted to make clear I'm not knocking your improvements (15% is very good) but in the long term, for me, things like brake-regeneration, start/stop, etc, etc, etc, in a new car might give me a better long term solution (but also cost more too). I'm not comparing apples with apples.
