from base boost to full power!

Awhile ago I posted a message concerning being stuck in base boost on my 1998 CSE (manual). The saab story began with a failed BCV that allow the turbo to overcharge up to fuel cutoff. After replacing the BCV, car did no better than base boost. I replaced the ECU under the expectation that the failed BCV had cause damage to the tranistor(s) in the ECU that drives the BCV. After swapping the ECU, still had base boost only.
Then I did some research in this board's archives and found mention of fuse #5 (which list listed as APU & heater pump ---> what's a heater pump?). That fuse was toast. After replacing it, all was well. I don't know if the original ECU had gone bad along with the fuse as I didn't bother putting it back in the car (the new ECU is tuned to stage2, so its prefered anyway).
Hope this message helps someone along the Saab road of life.
