Thanks Duncan for mapping my car today ( Vauxhall Astra 1.9 cdti SRi 150) .. the mpg went up from 40.4 to 53.4 on the run down to Blackpool which I'm very pleased about.
The run seemed to be a lot smoother too.
Just have to see what the bhp is up to now when I take it to the rolling road
Thanks Drew for the use of your facilities and your expert coffee making lol
