I don't know what the HKS fuel enrichment consists of but if it's a bolt on frequency valve bleeding off control pressure to enrichen the fuel mixture than it won't affect the WUR, and an adjustable WUR won't affect it.

They would be both doing the same thing - adjusting control pressure by bleeding fuel pressure out of the cavity on the top side of the control plunger cylinder and returning it to the fuel tank through the factory return line, but they would be doing it in parallel with each other so they wouldn't affect the operation of each other.
