Default MPG?

Well the Gryphon has been installed for a month now. I just made a 600+ mile trip and was wondering why...

My hand calculations for mpg were 15.75 mpg. The Gryphon display for average mpg showed 20.6 mpg as I was rolling into the driveway. That seems to be a HUGE discrepency.

I have the 87 tow tune loaded, tire size and diff. ratio are correctly loaded. Why such a huge difference?
