control pressure values for 3.4 liter with mods

I was looking to get a starting point on my initial WUR set up. I know alot of guys have been using a Leask WUR and have already dialed in their fuel heads so I was hoping to gain a little info to get me started in the right ballpark. From this starting point I can tweak my fuel control pressures to get adequate A/F ratio for my particular engine based upon its O2 sensor feedback.

My engine specs are the following:
stock Euro fuel head and injectors
3.4 liter with SC cams
ported intakes to 36mm
headers with K27S turbo and stock/gutted muffler
B&B intercooler
running 0.8bar boost for now

QUESTION: What is your system pressure and more importantly the warm control pressure you have your adjustable WUR set to?
What cold control pressures if you have the info as well?

1979 930 Turbo....3.4L, 7.5to1 comp, SC cams, B&B intercooler, Snow Perf water/meth injection, Rarlyl8 headers, Garret GTX turbo, 36mm ported intakes, Innovate Auxbox/LM-1, custom Manually Adjustable wastegate housing (0.8-1.1bar),--running 0.7bar max
