Subaru (SPT) claims that no additional tune is necessary on an otherwise stock engine with just the SPT intake and their SPT catback exhaust. You might assume similar results if your exhaust is a catback but if it is a full turboback system, I'd consider getting it tuned for best safe driveability and power.
