We always need a tune?

Oki..
I'm new to Subaru
I been reading forums like crazy because I don't wanna kill my Rex.
After reading all the forums I'm beginning to panic a bit lol
Is there anything we can add on to the car without tuning?
SRI for example?
Seems like every little thing we do to the car we need a tune
Is that true?
All I want to do is add SRI and Cat back,
I'm leaving BpV stacker ( from reading seems like its a good 1 with my little mods )

Yes even with the short ram you will need a tune. Think of it like this, the ecu controls everything related to air, fuel, boost, and timing. Anything that can potentially change that kind of stuff needs a tune. Now, the cbe does not need to be tuned for. (It's just a sound mod, no HP gains) Nor does a turbo inlet. But a short ram will make changes to the airflow very near the maf so they usually require a tune of some kind. Hope this helps.

buy parts and save up for a tune all at once or get ahold of phatron on nasioc or stimikey from phatbotti tuning and for half the price of a tuner at a shop they can hook it up.

Return the GFB valve and sell the intake. Junk.

Nope. That intake requires custom tuning to use. And tuning has nothing to do with the valve.

Yeah, welcome to the world of Perrin (junk). Which BPV (from GFB) did you even get? You dont need one, but that probably isnt your problem.

Thanks Paul, I will now go back and fix my post. I saw it was a GFB unit. Was wondering which one from them he got.

Yes, it requires custom tuning.
