trionic boost taper

Syptoms: Only in wet, humid weather I get a boost taper on max boost and engine missing at low revs. Idle is low and bouncing, but not too bad. Everything leads me to think its the DI. Classic symptoms. But I've checked it all.
3 different used DI's
new plugs
block temp sensor
intake temp sensor
throttle position sensor
cleaned idle control valve
various vacume checks
What would you do? I'm about to take it to a dealer for code checking. I was planning on checking the fuel presure and pulling the injectors to check the flow rates and spray patterns. But my problem has to be electical, because on a dry day the car is great. I'm starting to check out townsend site on trionic but they need isat and probing harness for the ECM. I've posted this on the 9k bb a few times but I'm gettin desperate. Guess what the weather is doing today in the northeast, US? Thanks in advance.
