Do you still have your OEM air filter? See if you can dyno it and K&N. All the flow tests I've seen show that OEM filter flows and filters better than K&N replacement.

AIB, can you post your dyno? I don't know why there is a dip in torque and hp at 4k RPM.

I had a much smaller dip or hesitation at around 4700.
