Still poor performance in my 98 900SE, now confirmed the turbo isn't bad. I installed one of those cheap boost guages like the hinda guys use, and I get 10psi in 3rd gear, 15psi or so upt ot the fuel cut if I unplug the wastegate, but still crappy performance overall.
I removed the bumper and checked all the fittings and found no boost leaks. It has to be something else non turbo related. I'm starting to suspect timing or engine management. Maybe the knock detect is improperly 'dialing back' my timing, though even that seems implausable. My other car runs better even on the cheapest low octane gas.
Thinkig of dumping this car and becoming a 'one saab' family again.
