It does have eds but nothing needs to be reset. Just fix the vacuum leak. I did 
have one once that had a bad rack position sensor in the IP which caused the 
eds to put it in limp mode with no boost. The fix in that case is was to send 
another IP I had on had out to get rebuilt, which was cheaper than sending the 
IP out that was in the car to get the bad sensor replaced. The other solution 
is to get a different turbo or waste gate that is pressure operated instead of 
vacuum operated.

There are dozens of vacuum lines on that car. Any one of them is probably 
become disconnected or had the rubber connector split or something. I had to 
replace a couple of connectors before Craig got it. It's probably got very 
little boost as well since a vacuum leak will cause the wastegate to not close.

There is a vacuum modulator on the drivers side of the tranny, slightly
towards the front, IIRC. Check the tubing going to it. Again, IIRC, there
is a rubber cap over the adjustment, which is a spring loaded shaft (small
dia.) with a small piece of rectangular metal at right angles to the shaft
which is seated in slots. You pull it out and rotate it one way or the
other, probably about 60 degrees, and try it to see what difference you
made.

However, what you are describing sounds like  no vacuum is making it to the
modulator. The adjuster thingy is for fine tuning the shifts.

Research the blue ufo and associated vacuum plumbing. There is also a
modulator on the tranny that can be adjusted, but fundamentally the blue
ufo's job is to soften the shifts at less than full throttle (or cold) by
altering the vacuum signal to the tranny, and therefore the transmission
clutch pressure. So be sure it is hooked up correctly to the injection and
vacuum pumps etc. All the ports on it are marked.

This is an issue with your vacuum system.  Any time you have hard shifts, 
you've either lost the vacuum signal or the controls that mange it are messed 
up.
