That way the MAF only measures actual flow entering the engine, and has no idea of what is blown off.

How large are those mafs? in inches that is... because I've been thinking of just bridging my maf signal to one and then bridging my temp signal to my stock maf sensor a little upstream of the big maf. (on the wrx's the temp sensor and maf are the same piece) That way I don't get the issue associated with turbulence that wrx are prone to when switching intakes and I wouldn't need to scale them. they do still work on a 0-5 volt scale correct?
