Turning fuel up on 940 Turbodiesel.
Discussion
Evening all.
Does anyone know which is the fuel screw on a 940 2.4 TD fuel pump? I've upped the boost slightly but I'm getting zero black smoke so I think its running lean.
Is it the screw right on top of the pump, in the middle of what looks like an enclosed diaphram type thing? There was a tuning guide on the old volvo forums but obviously I can;t get to it now.

Found it.
Just for reference, it's on the front of the pump, half way down with an inconspicuous plastic sleeve over it.
Winding it in a bit has made the world of difference to my car. It pulls better at lower revs and the turbo spools up a few hundred RPM sooner. Now for more boost...
