Cobb AP Perrin stage 1 Ok so I broke down and bought Cobb AP and loaded Perrin stage 1 Map and SPT catback. I will be installing catback tomorrow but installed Perrin Stage 1 93octane map and wow what a difference. Car is sees 15.2psi boost in 2-4 gears. It's like a new car. Can't wait till dyno day. Alain
I'm not sure man. I am new to the entire Subaru thing so still learning. I've been a mustang guy for a long time but really enjoying this car. I put the SPT exhaust on this morning and it sounds SWEET. You can hear the rumble of the motor now. I like it. Alain
