AFR Idle - 12.8
AFR Cruise - 14.0
AFR Redline under full boost <12.0
AFR 3000-4500 rpm under full boost - 11.0 in 3rd gear and <10.5 in 2nd (with side port of WUR open to atmosphere so the boost enrichment function was disabled)
All this is good until you get here:

I don't know how that is even possible. Without a boost signal the WCP would remain unchanged at ~3.7bar which would be very lean. I'm tuning a RarlyL8 modded 930 in the shop right now and this picture below is what you should see under boost (pressure at 0.75bar)



This is what you should see at 0.26bar before enrichment:
