CAI is not userful for our cars. Shorty intake, etc, CAN be useful if the engine needs better intake flow. The stock intake is good for at least 350hp engines.

That's my opinion and I'm not an expert.
the topic is on BOV here

regarding bov, I cant think of a way to tune for a bov (with a utec at least) Try to tune the fuel map to reach the target AFR. BOV only cause you to run rich for a short time. Not enough to make you stuble if the AFR is right.

dont add too much fuel on the 0% column to avoid shift knocks. I use flat timing accross the load sites above 4750rpm to get rid of those shift knocks.

the reason why BOV on stock impreza is a no no is because bone stock imprezas run pig rich (but I'm sure most ppl know that)
