I believe the biggest variable in MPG is the driver. I haven't even bothered to check mileage with the chip except the 3600 mile trip I made last summer pulling 10k horse trailer 12.5 mpg running 70-80mph on the 80dd. Just riding around I have not bothered because I haven't been able to run a tank of fuel through it without hitting the 120r tune for a little bit (just to make me smile). Like Bob said having that giddy-up without losing noticeable MPGs is more impressive to me. Just my opinion but I feel pretty confident that I could show an improvement if needed but still having to much fun.
