Well, its done... I had my Mystique PCM recalibrated to SVT specs. So far, here is what I've found:
-First of all, the car runs fine. No pinging, no misfire, no driveability concerns whatsoever.
-Low end seems improved. Subtle, but it is there. Mainly in throttle response. Power seems more linear.
-Strange side effect is that the temp guage reads much LOWER!

The guage has consistently read between the R and M in "NORMAL", and now it sits comfortably nestled in between the N and O.
-I have yet to test the speed limiter, if it is there at all anymore. No chance to get to an isolated highway this evening to open her up.
- I now have a Check Engine light, due to "running lean" condition. Those 19lb injectors should clear that right up later this week.
-I may have lost a bit of top end power, but once again, 19lb'ers will clear this right up.
I will follow up on this once I've tested the limiter and the 19lb injectors.
Any questions?
