Well we have tried two differant coils.
At this point I am suspecting either the mods we used are wrong, or there is a defect on the board itself. I am finishing up a small jumper harness now, so I can test out a V3.0 on my own car. I should be further along with a real answer by the end of the weekend.

Double check those hardware mods again. No trouble here with the older V2.2 boards running a variety of 7pin and 3pin VW ignition amplfiers. If you suspect the VB you can always wire either of those in, dwell 75% fixed for the 7pin and dwell on for the 3 pin.

I am no longer sure it IS an igniion issue. I had him setup everything with a 7pin module and still having the same exact issue. The datalogs are not as much help as I would have liked, due to only a NB fitted at the moment... But we are definatly seeing the motor go lean when it misfires.
And his boost gauge disagrees with the readings in his datalogs. I am suspecting the misfire is actualy a lean misfire as opposed to too much dwell.
As for the ECU mods, I used CdnDub's directions off the Tex. I am going to go back over them though. I am currently hacking into my own harness to go ahead and test everything out on a running car. Currently my car runs a V2.2 with a 7-pin IM. And I didn't make this first harness plug and play for either ECU like I have done since then... I think my car is going to get a new harness this week!
