i had a dyno today and the air to fuel ratio was 15:1. Not to mention that the dyno result were 328hp and 298 torque(yes it's an s2). there is no doubt that my torque number have gone way down since i got the s2. i dynoed one time at 352hp and 308 torque. but dynoed at 328 and 316 with just the s1. someone help me understand whats going on.
