I am running over 300 hp (365hp), and the stock computer has been
locking it at wot (95mph) for over a year, and at 300hp for a year
before that and I have not (yet) had any problems, but I do have an
aftermerket convertor that could potentitally be alot harder than any
of the stock convertors.

GM by default locks the 4th gen A4 at wot.  It is at a different
speed on the 93's than the 95+ cars but, I would hope that had
tested this sort of  thing enough to know how long it would last,
maybe I just got a good tranny, mine is past 115k on a high hp engine,
with only a shift kit and better higher slip torque convertor added.
