Hello,
my early 91' 9000 T16 recently had a minor engine rebuild and I get turbo boost problems ever since.

The turbo boost gauge goes to the begining of the red zone when I accelerate hard (1 bar measured with a calibrated boost gauge) and 1 or 2 seconds after it loses power and boost(to 0,4 bar, gauge at yellow).
The really strange thing is this don't happen at speeds of 100 mph (+/- 4000rpm) and above, with the pulling strongly as ever.

I replaced the DI unit at about 140.000km, the car as 180.000 km now.
It never occured before the engine rebuild (valves, timming chain, etc). I ran it for two years with only minor faults and allways go great.

I've searched the thread but I don't think that someone reported this problem.

If some of you could help I appreciate. I leave in Portugal and here Saab engines are something of the devil's work for the mechanics. No one have a faint clue of what's going on.


Thank you in advance,

Claudio Neto
