Sounds like alot of thought went into decreasing your intake temps. I am a little leary of the hood modification though. I hope it never decides to pop open on ya and fly up blocking your view. One thing I did notice. You still have the OEM air intake elbow on your TB. I wonder if you replaced that one with a solid smooth bore elbow and coated it with a ceramic paint, would that reduce intake temps even further. Just a thought.
