I'd venture to guess that it's the same thing as most of the intakes for the Evo X, MAF sensors being placed to close to the intake filter causing issues and almost necessitating a tune/reflash. Whereas the intakes that had the MAF sensors further downstream of the filter had no need for fuel correction and worked as intended.
I'd suggest looking into MAF placement honestly, this definitely isn't the first time I've heard of this occuring.
