Yes, the 4mm allen head for warm CP adjustment on the bottom does affect idle and steady cruise AFR to a real small degree if you turn it only 1/4 turn at a time.
Brian had mine set at 4bar for steady cruise.
If you have the instruction manual he gives you with it I'm talking about figures 2A and 2B.
If you want to lower boost CP to get more fuel on boost after doing that then use the tool he gives you to draw out the steel disc on the bottom in figure 3A.

After doing all that you may have to do a fine adjustemnt on the cold start CP on the top of the WUR.

I have a flowtech IA modified fuel head that flows +20% under boost so my CP's are tuned around that fuel head and will be different than a stock fuel head.
I have CIS gauges and very rarely use them on my car. I adjusted the WUR and system pressure on the fuel head by experimenting alot, road testing, and a wideband AFR gauge.
