Car drives mint already, no flat spots, nice and responsive etc.
Car makes reasonable power already.

The BIG fault though is that it is poor fuel economy on cruise on the motorway.

I bet that just by advancing the timing in literally a handful of cells, and leaning it out a touch in a handfull of cells, in the space of literally 2 minutes, I can add 5% at least to its fuel economy!

Im sure Stu or Karl could do far better, but they are running a business and so charge more than a cup of tea which is the value I place on my own time, lol

Si's spec will move on later on, this is just to allow him to be more econimical in the mean time.
