They were robbed blind.  I fix things like this on MBs for pints of

Heh.  A basic health check (as I implied) is in order.

To a sick car?  Usually not.  To a healthy one, when you understand what
the chip does, what you're trying to achieve, and the other things you
need to do?  Yes - there are people on this list who've done that.

I might also add that a "Superchips" chip (for an MB engine) has
recently undergone some scrutiny by member(s) of the QLCC.  Maybe they
will comment here, and maybe not.   Their choice.  The car in question
was one of those I alluded to; it had a defective WOT switch and other
problems.  With the Superchips chip replaced with a stock chip, the
wastegate shims thrown over a hedge (literally - at the Robin Hood
about three months ago) and a new WOT switch, the owner is grinning all
over his face.  Unless someone mentions 'chipping' ...
