Well I checked my pump timing as I have never gotten around to it since buying the car almost 2 years ago. Following the procedure in the FSM my timing is 0.775mm. The book states:
"
D24 (exc. USA/Canada) : 0.90mm
D24 USA/Canada 82-83 : 0.80mm
D24 USA Federal/Canada 84-? : 0.85mm
USA Calf. 1984-? : 0.75mm"
So it appears the car is timed to California specifications ... we can do better than that.
My plan was to time it to 0.85mm, which puts me right at the US Federal specification. Of course the Rest Of World spec. of 0.90mm might be a better choice.
However I did note on the VolvoTurboDiesel blog that 0.95mm was the hot ticket:

So what are the thoughts of the collective? 0.85mm, 0.90mm, or even more advance? My car runs "fine", but its all I've known from it. Peppy, easier starting, better MPG are all attributes I'm hoping for, perhaps > 0.90mm is the way to go?
