hello im a nooby here. I have a 03 subaru wrx sedan. my mods are turboback,uppipe/headers, and cold air intake. I heard that i can flash my own car and all i need is the port cable from tacktrix.com is this true? my question is where can i get maps for the mods on my car right now so i can flash it? are the maps free? if not how much are they?
