You replaced your '86 WUR with a known good '79 and still get the same result. I'd put the '86 WUR back on and assume that isn't the problem.

You need warm fuel pressure data, boost fuel pressure data and AFRs.

If your fuel pressures are in spec you can assume you are getting the right amount of fuel. The other element of the ratio is air. Is your air filter clean? Do you have a catalytic converter? Is is free flowing? Is your ignition healthy? Good strong spark and clean plugs?
