I 'm a noob to the wrx But a quick learner all ready have plans to void the warranty on my 2012 with 565 mi. Always open to advice and knowledge. Just want to build it once. Near future plans include air intake,Invidia Q300 catback and high flow cat down pipe, and a Pro tune. all in the next 6mo, I hope. If any one knows a good tuner in the southern NH area (dyno) it would be helpful. Subaru of Manchester recommended Bren tuning any one ever heard of him?
