OK now that Bob has come forward the adjustment I made he is speaking of is the large one to the right of the idle fuel adjustment....my car has half the miles on it his did which could explain why mine is overfueling at half the optimum adjsutment for his.

This is the one that is causing me problems with idle speed and its reluctance to return to idle.....the one that at three turns out had it idling at 3,400 rpm and at 1.5 turns out had it idling at 900 but slow to return to that speed. And this being still too far out to suit me even though the EGT is still just in spec...there is no doubt this adjsutment does increase the fuel delivery also, Brian Carlton has followed my car during a full throttle pullaway from an intersection.

Becasue we have been told by some that adjsutments on this pump are inter related with others I am wondering if one does so with a low end bias and the other with a high end bias. It still would be nice to get the word of an Bosche tech to verify this.

I will be pulling my IP again to zero out this adjustment back to original spec...and try Brandons...to see if I have less driveability issues with that adjustment. But that may be a couple days before I can do it.
