hey sorry if this is posted somewhere else, if it has i havent found it. I have a GT with K&N FIPK CAI, and magnaflow mufflers. My car is naturally aspirated, i have no turbo or supercharger with a stock PCM. It says to run my car on regular octane. Would i see any benafits at all if i go to premium? would i get a few extra hp?? or would it just rape my car? thanks guys.
