The standard average MPG indicator is functioning normally.

I recently installed a Perrin CAI. Not sure if it was on the fritz prior to this.
What you're monitoring is the "real-time" MPG, so obviously it vary wildly depending on throttle position, gear, speed, etc, etc.

127 is the max of the display range. When you lift, the ECU shuts off fuel delivery, so the real-time MPG is actually infinity, but since our ECU doesn't display infinity, it defaults to max display value of 127.
