I am experiencing a problem with boost on my 94 9000 Aero. There are 2 sets of symptoms. 1) The turbo over-boosts leading to the engine cutting out. This happens most days under full throttle acceleration. I can prevent this from happening by modulating boost with the accelerator. The needle on the boost gauge goes way past the red zone before the engine cuts out. If I modulate boost with the accelerator I can allow the needle to go a short ways beyond the red zone before the engine cuts out. 2) Other days, full throttle acceleration results in minimal boost with the needle on the boost gauge only going about halfway into the red zone. I reported both of these symptoms to the mechanic at the Saab dealership when the car was in for its 65K service but they did not fix it. I only burn premium from Mobil, otherwise I could blame the gas when I experience minimal boost. Any thoughts on cause and remedy? If I need to take the car in for service I would like to be educated on the issue before hearing what the mechanic says. Thanks, Jeff
