I just read through some Steve's old posts to refresh my memory...
There have been other failures reported since then that sound pretty similar but who knows what the cause is? Out of curiosity, has the engine been rebuilt stock/modified or is it a pull from another vehicle?
Given the history the very first thing I would do is check the MAF if that hasn't been done already, if it's a pulled engine I'd want to check the head torque and for sludge, and after that I'd immediatley weld a bung in the exhaust and install a wide band 02 sensor w/data logging capability. Also considering the history it probably wouldn't hurt to monitor your EGT's as well. I don't have one of these because I didn't know about them at the time I bought my Wego unit, but it seems like the Zeitronics (Zietronics (?)) unit is a pretty cost effective solution. In any case, if it were me I'd really install some monitoring equipment before getting on the boost real hard with your current setup.
Yes, Steve had a dyno run that showed 12:1 AF for the duration, but that was only under one single test condition--and his engine did self destruct for SOME reason.
