I am not sure (but others will comment, no doubt) but if you compare with a non-turbo engine, it pinks when the revs are too low for the gear but is less likely to pink at higher revs. That is what is happening here. I used to tow with a 9000 2.3t fpt and it surged as you describe if the fuel octane was too low. At the same time the turbo gauge pulsed. You might also try Shell Optimax, that is supposed to "suit" Saab turbo engines.
