Chipped mileage?

[Mike Del Tergo]

Curious to beat another thread to death.  Currently getting 21MPG hwy for 
Hohenester chipped 2.5P ransduced 20V Avant.  Just took a 600 mile trip with 
less than 3 x on ramp/merge slach warp speed passes with cruise set to 75.  
I'm not really willing to accept a 20% MPG drop from my usual for very 
occassional 270HP bursts, better throttle response all around excepted.  
Just curious to see what others are getting and the chips they are running.
