  .88 is the "proper" timing setting for that pump.  (I've only seen it 
come factory, from Rabbit pickups) The .93mm is the "performance" 
setting if the 40mph to 60mph (or something like that) acceleration 
time is too slow.  I wouldn't set ANY lower than .88mm unless you 
like the feel of a TD Benz with a plugged exhaust and a frozen turbo!
  If you were driving strictly in town and loafing along I could see where 
you MIGHT get a little better mileage with a more retarded setting.  
Otherwise I suspect you'll not only have less power and sluggish 
acceleratino but poorer mileage as well.  Might not start as well also.
