2005 Forester XT
Hello all, I am new to tuning/modding cars and was just wondering if i need a protune/cobb accessport to run a catback exhaust efficiently
It does sound like it - Unless the ECU for the American market was locked or runs on different programming... Unlikely but possible since you have additional emission codes and a different PCV valve setup.I was told by the local tune shop that i need to have the tuning box (cobb accessport) in order to have a custom tune done on my car. Are they trying to rip me off of $650?
