So, mine seems much improved after fixing my leak at the intercooler pipe.
Previously I had put in a new MAF sensor, which slightly improved things.
Also,
the dealer replaced the 11-74-7-626-351 Pressure Converter (Boost Solenoid),
and flashed the latest software as of Sep-1 2016 (there is no indication of version or part #).
All of this seems to have made the difference, and for today, it's running much better. No idle fluctuations or stalling, and so far no more running too rich code. We'll see if it makes it a full week w/o issue...
