This can only be speculation; who's to say to what degree the SVX's single resonator influences the intake?
Reading williaty's thread, he's proven that at low RPM, the MAF gets all sorts of confused without any resonators. Any bit of air that gets pulsed backward through the MAF causes a volume reading increase equal to that pulse, while the true volume is actually reduced by that amount.
The dyno readings of the TomMyx shown don't reflect the 1k-2k RPM range where williaty's readings show the MAF reporting substantially incorrect volumes.
It's not the difference of removing one being fewer than removing two. It's the difference between removing two out of three and removing
all.
If only for the fact that I have no evidence to believe otherwise, I can't say that this is an issue with the SVX. The obvious similarities to the Impreza should lend to that there
could be a comparable situation, though.
It would be interesting to see this tested before any hasty statements are made.
