turbo boost issues

My 1997 CSE automatic (130K km) is still showing fluctuating boost on acceleration. APC changed a few weeks ago when the maximum boost that could be reached was mid-yellow. Now giving mid-yellow to mid-red on acceleration with oscillation (mid-yellow to mid-red). Pressure changes confimed with SAAB diagnostic tool. BPV (original) at 25% with max boost. No fault codes being recorded. Fuel cut-off achieved several times. This is not a continuous problem. When not doing this boost pressure is at first yellow bar on hard acceleration in 2nd/3rd gear (186 kPa). All vacuum lines seem OK. The mechanic is not sure where to start. Anybody encountered this problem, and if so, what's the answer?
