I have seen quite a NZ guys running the AFM in that position after the I/C. Its and interesting
idea in principle you get post I/C temp reading by the afm plus a boost cut that allows for
pressure drop over you piping etc etc. The down side is with the reversion of air off pedal if
the BOV doesn't vent enough air the reversion will cause the AFM to close causing both a
restriction and also a lean condition by means of a reduced air signal by the vane closing.
I personally wouldn't run anything over 3-5psi without and I/C think about it if a manufacturer
puts and i/c on cars running 7psi for longgevity and a factory I/C can be had for very
few $ then you would really be a fool not to use one.
