What is the vacume pressure spose to sit at on idle? Mine is -75kpa in P and about 61kpa in gear... does this sound correct?
Also a slight vacume leak will raise or lower the idle? I ask this as today I was tidying up the Wolfs wiring and tightned a few clamps on the vac hose that runs off the fuel reg to the boost guage and ecu. When I started it up it now idles at 1400 rpm in P... what have I done here?

Haha - metric boy!! Mine idles between 21inches mercury to 19inches mercury of vacuum.... should be similar for all engines. See link:

Where 6.9kpa = 2.03 inches/hg

Therefore 69kpa = 20.3 inches/hg

So i'd say 75kpa roughly 21inches.... seems like yours is all good...

Vac leak should raise idle... example being the idle speed controller - this is simply a computer controlled vac leak to increase idle.

Maybe your inital tune was done using incorrect manif vac at idle?!?

Hmmm, maybe, I'll have to see how it drives then.

Initial tune? hehe, its an ongoing tune... I fiddle with the pulse widths ever time I drive it.

Thanks for that

I thought if you had a small vaccum leak around the map it would increase idle due to the ecu dumping more fuel in. Less vaccum usually means more fuel, which would raise idle a bit.
