I got to thinking yesterday at work about why the air mass meter is right after the air filter itself. Why couldn't it be closer to the throttle body? I want to use a atmospheric BOV on my car and putting it up closer to the throttle body would fix/help the problem with riching out. Saab more than likely wanted to put it right after the filter so that they could use the quiet recirculating valves. Only reasons I could think of not to do this was any oil from the turbo getting on the AMM itself or it not holding up to the boost from the turbo?

One possible reason is the extremes of temperature it might have to work in- particularly on cars without intercoolers, as the turbo significantly heats the intake air.
It might also have dificulty coping with the rate of rise in intake temp- it uses a hot wire metering system.

I think it's worth a shot, my car does have an intercooler. And I would think it has a pretty good temperature range just from the normal fluctuations in ambient air temperature. I'll get a hold of a backup AMM and give it a shot, and be sure to post what I find out. If anyone else can think of a reason this wouldn't work, I'm all ears!
