"I did plenty of research between protune and the accessport and decided to go accessport. If you want to gradually do modifications to your car like me then this is the way to go. As for power I did notice alot of power in the higher RPMs from stock to stage 1+ with an aem cai. I did expect a lot of more power after reading reviews on the accessport so their was a slight let down but it's definitely worth it. This is a must for people who want to mod their vehicle but don't want to go crazy." —Stephen S from Bridgewater, MA bought a COBB AccessPORT V2 Tuner for a 2013 Subaru Impreza.
