Expected cruising boost

[Dr Gary]

DDi 3.0 (not common rail)
Does anyone know the expected unmodified boost pressure when cruising around 90 - 100 km/hr.
Alternatively, what pressures are you experiencing??
Seems I get between 9 and 12 psi without much throttle.
Checking small stuff as I have a brand new rebuild to run in.

I have the same motor with dawes and I get about that reading. long haul at 100k sits on 10psi when crusing, so 9 to 12 sound about right. I limit it at 15psi but you really have to put the boot in to get it over 12 or so. Hope that helps. Cheers Tony

10 @ 100 on the highway.
16 max.

X2 10psi @ 100kph is the norm what are you driving manual or auto
as that will be different revs at 100 kph

So with the knowledgeable responses I am satisfied that I have it about right. Thanks to all.
