I agre, I think the power moduel would be overkill.

And on the hyd. pump with the mechanical head.  Take it out and go stock.
My montor thought that too much oil being pumped around could only be a good
thing, not true.  1) The oil stays up in the head, not at the pickup which
then causes 2) extensive foaming, especially if you have a close-ratio
tranny and like to fart-around on the highway.  My oil temp as also
stupid-high, like 120*.  I replaced it with the stock unit, and found that
it was much more liveable, and the oil did not foam nearly as much.

Long-story=short, the hydro oil pump best serves the hydro head.  IIRC, TT
also corroborates this somewheres...
