Ah sorry Alex i forgot it was the wrx. On the sti you gained about 30bhp, i don't see why you could not get the same bhp increase as it would be relative. Consider an uprated fuel pump also as well as the map, think we have touched on this before ☺
a PPP upgrade for the the hatch that created the 330s was effectively a prodrive back box, filter and remap
for a full system check out Milltek

for a car this new I if you just want the backbox go for a bolt on option - less hassle and you can fit it yourself on your drive. The Prodrive one I had on mine was great quality
depends on how much you want to spend??
Sorry it was SVA imports

Wotcha and welcome. The pack could well consist of a remap backbox & filter in which case the only way to be certain is session with a mapper as the exhaust and filter may have been changed since the original mod
I so would, things have turned around in last couple of weeks but too soon for something like this unfortunately otherwise i would be right there [emoji7]
Wotcha and welcome - best way for photos is to host them on something like photobucket and post a link that way you get high res stuff the forum wont allow
Wotcha and welcome - if you scroll down the forum categories you will find the market place with for sale - wanted sections etc

in theory yes that will work - you may have issues though if the spring tensions are different meaning the valve will activate at different pressures, why not run without the BOV fitted until you get a replacement?
