When I unplug the WUR...It runs similar but I with a bouncing tach and then stalls but as long as I don't have to stop at a red light when I'm driving it is so much fun.

You already did your keep the car thinking it is cold test.
Running blind until you get a set of gages on there and see what the pressures are when it runs well and when it runs badly. The bouncy tach is likely idle oscillation that occurs when the mixture is too rich and would be consistent with unplugging the WUR.
Is the Lambda system still intact? Is the O2 sensor still in place? Failure mode for the Lambda system is a lean condition, which you are describing. Vacuum leaks also create a lean condition. Has your car backfired or had a hiccup lately? Cracks in the air box are a common vacuum leak source. A few things can cause these symptoms. Verify your fuel pressures then check for vac leaks including the airbox. If you have an AFR meter that will help also.
