ECU Tuning

[Comet31]

Hey, I have an 07 specB, the non GT 3.0r 6 speed manual. im interested in possibly adding a custom ait intake (https://raptorsc.com.au/subaru/subaru-l ... -cai-kits/)
and im curious about how hard it would be to tune the ecu. Its my understanding that a bigger intake makes higher pressure so ill have to upgrade fuel pump as well as injectors. Anyone have any similar experience or advice to how to approach this. Don't want to lock out an ecu. Maybe a laptop software to program through OBDII. Any advice would be helpful cheers. (also there's no many places in WA that'll tune a Subaru and not charge you 3k)

Bigger or more free flowing !?

If you change the diameter of the tube/housing that holds the MAF sensor then you will need to re-tune (i.e re-scale). But if it is same size, just flowing a bit better then you won't need to make any other changes. I think your pump and injectors will be more than adequate. Of course a tune can net further improvements.

Buy a Tactrix, install Romraider & ecuflash, get the ecu etuned for your mods?

Etune via eg Sick Chips, ThrottleHappy or Torqued Performance?

Then use Btssm on Android with the tactrix or a $15 vagcom kkl 409.1 for logging your state of tune, virtual gauges & learning view?
