So I recently purchased a 2004 wrx sedan. it had about 96,000 on it. It was a great buy and i love driving it everyday. Mods so far are few.....uppipe, hks catback, and silencer delete. I'm kinda a hands on learning type of guy. I've been looking into tuners like open source and cobb access port. still kinda of confusing as which one is better for me. I live in yuma az and there arent alot of tuning places around here for an opensource. I want to do future mods like dp, front mount intercooler, fuel injectors and wastegate. I want to get my powerlevel to about 320-350 hp and tq but at the same time want it to be drivable on the street. help with mods list to get me there the cheapest way? thanks!!!
