this is the 1st saab i've owned so i don't know how it compares to others performance wise. its a 97 aero. it had been off the road for a couple of years when i bought it. i fitted a jetex system and a forge dump valve last night but i was dissapointed with the performance of the car. compared to my 1989 bmw 325i its pretty dull. the boost gauge needle is half way up the yellow when on boost. what should a standard cars boost show on the gauge? you can't hear the dump valve either which also makes me think it may be down on boost. any advise guys? cheers.
