MPG is low
I'm running a 2001 FLHTCI and getting about 35 mpg, riding one up and I wight about 225 lbs. Stock pipes, screaming eagle air cleaner and that's it. I'm not heavy on the throttle. I ride about 70 on the highway. This bike just seems to guzzle fuel. I recently had an M&M tune up for the FI. Bike has 44k miles. Any way to improve this? e.g. Less weight? Different oil or trans fluid?

The dealer cleaned the FI system and made sure all the settings were at factory-specified levels.

I have a 2001 Flhtcui and I am converting to carb. I upgraded my motor to high compression 103" and the MM system is to finicky to handle that much upgrade. If your going to stay mostly stock to a mild 95" build I have a MM SERT that is 4 months old and the ECM that came off the bike I will let go for $250 plus shipping. With the SERT a tuner couldmake adjustment to the ECM for your build.

RE: MPG is low
I've got the MM system on my 99 RKC, and I don't get the best mileage either. I think I'm in the 35-40 range, but it depends on many factors. I would start by checking your tire pressures. Having low pressure can consume 1-2mpg on a car, so it's worth checking on the bike. Also, where are you located, what part of the country? In cold weather, my mileage drops by about 15%. I ride with a shield and bags, so that will drop the mileage. Finally, do you warm the bike up for a few minutes or just drive away immediately?
