Hi Phil,

I've had a bit of a rethink and some remembering & would agree with John Parker that the highest vacuum readings would be the way to go with DCOE's. I also say that you can gain economy by extra leaning out & subsequent reduction in vacuum when using SU's or injection. The reason for the difference would be that SU's & injection have superior fuel atomization over a very wide range of rpms. OTOH, it is very easy to get into excessive lean backfires with DCOE's especially with the typical softmounts being leaky. (Volvo's own softmounts are awesome.)

Cheers,
Paul.
