Hi guys, so I have a 2013 wrx and I am looking to get some extra power out of it. Besides buying an accessport, or going with an opensource tune or pro tune, what can I do to get the most power out of my car? Right now its completely stock, and my tuning budget to less than a grand at the moment. What do you all suggest I do for an optimum increase in output with my restricted budget? Intake, exhaust, etc? Thanks for the help!
