Hello...

Can someone please shed some light on this dillemma..

I have done tonnes of research and consulted many forums but im going NOWHERE!!

I have a Subaru Version 5 2 door sti Australian delivered.
Has a Apexi power FC specific to the V5 V6 GC8 SERIAL NO PFC GC8F 020

My car came out with the following STOCK AFM or MAF
GREEN LABEL 22794AA010 (this is the stock AFM for a version 5.)

I now want to run an AFM from a version 3/4 Subaru gc8
ORANGE LABEL 22680 AA271.
As im going up in power to about 230kw ATW on E85 and need a STABLE MAF

I dont want to go z32 or Q45

These are the questions i have..

The only real questions i have are...

1. Those who have tried the conversion is it a stable and trustworthy AFM and can it handle is HP level.
2 . Once its wired in properly how do i select the MAF in the power FC?

There are 4 options available when i bring up the page

1.-GC8 Normal
2.-Super Intake
3.-80mm VG30
4.-90mm Vh41
5.-Option

My question is which one do i choose?.. The power Fc is obviously configured for my version 5...
So if i install a v3/V4 orange sticker MAF and CHOOSE OPTION 1.-GC8 Normal will this be ok?

As you know there is no edit button so i dont want to make a mistake..

cheers and thanks in advance..
