I recently bought a used 2008 WRX Sedan with a K&N intake and SPT Catback Exhaust. The original owner said that the K&N intake and exhaust were dealer installed. He told me that the dealer MIGHT HAVE did a "flash" on the car for the intake, but was unsure. So I just purchased a Cobb Accessport v3 and am wondering what stage 1 "map" or "tune" to run off the Accessport with a K&N? I see on Cobb that they have a map for the Cobb SF intake and AEM, however none for a K&N. Which one should I use? Or am I SOL?
Any help is appreciated!
