A bad BPC valve produced similar symptoms on my 91T. I would consistently get a little more than base boost, and sometimes a burst more that would quickly cut back. I replaced the BPC valve, did an adaption run and I am back in business.
Of course, it could be the knock sensor, which is on the back of the block, about half way down. It's very hard to see because it is below the intake manifold. There are 2 sensors down there. The knock sensor is the sensor with 2 wires. I also cleaned the knock sensor electrical connector with a wire brush and packed it with dialectric grease. I did the same for the intake air sensor connector, which is on the metal tube going to the throttle intake.
