It is generally accepted to target boost AFR at 11.8 +/- 0.2 :1
An adjustable WUR can allow you to manually adjust the boost control pressure as well as cold, warm and threshold. Typically the DIY adjustable WUR will only address the cold pressure as it is most problematic on old units.
Again, you may not need this at all and won't know until the AFR's are measured. That is best done with an LM-1 or on a dyno. A data logger is required as you do not want to be looking at anything but the road when on boost.
