I am getting a wrx from a guy i know, hopefully this week. He is giving it to me with full exhaust, an uppipe, and a downpipe. I was wondering what i should get next. I am looking at the ecutek reflash and on the site it claims 40 whp, i was wondering if that was true, what exactly it does, and is it worth it? i also plan on gettinng a boost and egt gauge, and a hks blow off valve with a recirculation hose. Any thoughts or opinions on this would be much apreciated. i am new to wrx's so there is a lot i need to learn i and would like to hear what you guys think.
