Retarding the timing would tend to encourage incomplete combustion, which
should reduce economy.

In the TDI world, setting the static timing to the 'advanced side of the
range' would maximize the opportunity for optimum combustion by allowing the
ECU to 'get' the most possible advance that it might call for.  I suspect
this is probably not true for mechanical pumps.
