Morning Dave,

Yep, I think you have got it. I didn't take note of the reading at idle but from memory that figure is about the same as mine. I was told the figure at WOT should be at least 500 which is about what you have captured.

As I previously said I am not interested in the "why's and wherefores" on why the reading is low. The customer appeared to doubt the validity of the re-map and probably thought I was a cowboy trying it on. If he had been more amenable and accepted that he had a problem with the car I would have got more involved.

Thanks Dave (again) for taking an interest and the time for providing your help.

Regards

Pete
