Wow, from reading everyone's mileage, something is clearly wrong, either with my calculations or the map. I divide the mileage on the trip by the gallons I filled since last fill up and I always reset the trip every fill up - always is between 35.5 and 37, two up or not. I shift between 2500 and 3K, 3K being max, usually when I am going from 5th to 6th. I guess I need to dive into this ecm and see what map is in there. I am a carb guy so this should be fun...guessing I can pull the ecm off and hook it up to my computer, or bring my laptop out to the garage and hook it up there - will have to read up on that more, I am sure there are hundreds of posts on that.

I'm curious. Most folks I know are getting 45~50 mpg on their touring bike 88's. I have a 2006 ultra with a stage 1 air filter and Screaming Eagle slip-ons. Other than that, the bike is stock and I always use premium gas. The stage 1 download has been installed. I get a consistant 40 mpg +/- one or two combined city and highway. My low fuel light always comes on, within a couple of miles, at 160. I then pump very close to 4 gallons. Why the difference? I'm not what you would call an "aggressive" rider so I'm baffled. Every other bike I've had beat the pack by several mpg.
Thanks for any thoughts.

I have a 09 ultra with the fuel moto jackpot mufflers pcv/at and air cleaner. I am using there mpg map and get 41 around town. Before I changed to the mpg map I was getting 38 on the interstate. Have not been on a trip since I changed maps, but am happy with the around town mileage.
I do the math to figure out mileage and am careful to fill to the same spot in tank each time.
