MarkD - any recommendations on which MAF to go with if you're upgrading anyways? Most people say that the Euro / v8 HFM hits 5 volts / flat line at around 8-9 pounds of boost in an s50. I would ASSume that the m20 wouldn't hit that limit at the same boost levels.

I have not got any recommendation for FI cars yet. (I know what I would pick for a n/a M20). I wish I had a car to experiment with for a few weeks. If a MAF maxes out with a certain airflow, what you can do is remove the sensor from the body (tube) and insert it in a body with a bigger diameter, then it will not max out. But then you need to change the software to account for that. Maybe I just have to buy a project car and add a turbo, do all the magic on it and sell it afterwards. Anyway, the Bosch HFM5 as used on the E46 M3 is a possible MAF to use, but it's not a direct drop in. (both physically and electrically)
