Appropriate CIS fuel pressure readings

[Arminho]

Pressure reading at cold start is at 1.5 bar.
Pressure reading after running 5-8 minutes idle is at 2.9 bar.

Background info: 1974 original 2.7L engine. Project for dad and I. All new hoses and gaskets, new fuel lines, chain tensioner upgrade kit, new injectors, new airbox, lower valve covers replaced(still need to replace uppers), rebuilt FD and WUR, new heat exchangers, new muffler, new spark plugs and spark plug wire kit, new fuel pump, fuel filter, fuel accumulator etc. Compression tested ok.
The WUR is a rebuilt 029 warm up regulator. Are these pressures appropriate? The Bosch jetronic/CIS manual doesn’t specify any pressures for the 029 WUR. I think it lists 3 types of WURs for the 911/911s pages and these would seem to fall within spec.

Right now, idle is still high at around 1050-1100 rpm.

Can anyone comment if these pressures are appropriate?
