It doesn't like it though. You can feel it begging to change up after
4500, and someone (Badger?) said something once about it being quite
bad for the lifters as they pump up.... Or something....

After the new cam mine was noticeably happier to rev and felt OK up to
5000. There isn't much to be gained up there though - it doesn't seem
to produce much more power beyond the mid 4000's. Oddly the new cam
didn't seem to do anything for the fuel economy though, although there
was other buggering about for LPG done at the same time so it wasn't a
true comparison.

Back to the OP - are there are any visible problems such as erratic
idle, colourful smoke or misfiring? Does your friend live at the top
of a mountain - not joking, when I moved away from Sheffield (where
everything is on a steep hill) my Peugeot of the day used a lot less
fuel.
