I may be incorrect, but, I don't believe that the MAF will read correctly because it was designed to work in the 4 inch(or so) air intake system, calculate velocity, and determine volume with respect to that area. With the velocity being considerably greater due to the restriction readings will have to be adjusted accordingly.
That is why the MAF doesn't want the SIR in front of it, as it will direct the airstream only on the middle of the wire. Causing way out readings.
This is just a SWAG(Scientific Wild Ass Guess). I pick up my E36 this coming weekend and am looking to learn all I can, and help where ever possible.
Thanks
