power loss / no power gain. . .

Is this a new car or something you noticed over time? The turbo craps out a little above 4k rpm's, and they are slow to begin with in stock form. You can get your ecu scanned for fault codes that don't trigger the CEL and post them if there are any.

Boost leak, or your DV is getting stuck open (depending on what DV you have). I have a early 99 1.8tq. Before I bought it someone bought a POS vacuum line for the run from the intake manifold to the DV. It would randomly pop off of the DV and would create the problems that you speak of. A little bit of boost, but no real umppff...... ECU never detected a positive deviation??? Other times my aftermarket DV would get stuck open and would randomly close, causing weird boost. Just start checking your vacuum and boost lines to make sure you don't have a boost leak.

'quoted for truth'- or 'quite f*ckin true' depending on who you ask.
installing a boost gauge is a very good idea, theres really no easy way of troubleshooting your turbocharged car without one. its a cheap and simple install everyone with a turbo or supercharger should do.
