Yet another WUR/CIS fuel thread

So I've installed my new UTCIS on the track car and am anxiously awaiting the arrival of my LM-2 to correctly tune it.. However on the 86 STOCK turbo theres a few issues to be resolved so I'm looking for some advice. Here's a summary of where I'm at..
It runs rich , when turbo kicks in it's black smoke, and sometimes some bucking..
If I lean it out I can't start it without pulling the air filter and pressing down the throttle plate to give it a bit of a "prime".. Also have a tough time adjusting the idle low enough
Just ran a pressure test on the "cold " WUR ( although it's 95 degrees in my garage here today).. system pressure is 6.7Bar and control pressure is 3.0 Bar..
Haven't run it "warm" yet..
So questions.. what other tests are relevant??
What would indicate a bad WUR ??
If it is a bad WuR do you think I could take the good one from my Euro 79 engine ( that was running great before I put the UTCIS on it)? Its a different P/N and obviously doesn't use the Lambda control on the engine it came from.
