kk,
the site u posted is a subaru STI forum, it may or may not apply 2 our mitsubishi, but one thing that we can apply is the relocation of MAF like wat they said....
however, i've asked around many ppl including some US folks in some DSM forums, also the famous boschur racing in US for some related MAF Translator products, all the conclusions come back to me is that the relocation of our mitsubishi MAF for a blow thru will have few probs, one is the accuracy of data sensed by the air flow, it may go haywire or providing inconsistent data which is dangerous, remember we need consistent high air flow feeding the ECU at high revs, this is to instruct the injector to 'ejaculate' more fuel, if this fails or something goes wrong somewhere, ur risking ur pocket on an engine overhaul....
another problem for MAF is we need the honeycomb to make the air shooting straight, there can be no room for turbulence coz the MAF can't read the air properly, n u need 2 b sure if those are OK, another prob might be there might be oily residue of particles within that particular pressurised chamber, so this might kill your MAF quick...
in a perfect world, relocating ur MAF should be done just before the throttle body, i would prefer the BOV to be installed before the MAF to cure for unmetered air disease as we've discussed....
