The limitation from what I've seen is that the BMW computer has really aggressive programming compared to a lot of other cars, the computer does not balance the timing well under boost and the rising rate fuel regulator is not fine enough control to let the computer balance the charge well.
It seems to be systemic of Bosch controlled engines..
The VIper survives because the V10 is a full fly by wire engine, and does a lot of tuning to keep itself in one piece, a side effect of that programming is the ability for the computer to adapt ot crazy fuel air ratios...
Just some random thoughts..
