Ok, the obvious answer is what did you expect? But! I've got an 07 Ultra with 103 kit and woods 6-6 cam. It's also got Doherty powerpacc and SPOs. Jamie supplied a basemap for the power commander III but I've not had it tweaked yet. Problem is I'm getting 135 miles from a tank with normal riding (70 mph) on the motorway. With where fuel costs have gone over here I'm paying over $33 to fill up so that's quite painful. The advice is, for those who've gone this route, is 135 about right or can I get more with proper mapping?

Thanks in advance.

 

I have gone as far as 175 miles with my 5 gallon tank and did not touch the reserve (non EFI). I would think you should be able to do a lot better than that.

 

I am having issues, with mine, I had my bike tuned by the dealer, have only ran 2 tanks in it due to work.
I am only getting about 120miles out of 4.8 gallons , Mine will be going back to the dealer for tuning, they said they want to look at it, because it can not be right.
Mine pops on deceleration too.
Smells rich as a pig in the garage after a ride.

 

Sounds like you need to get your bike dyno tuned, one would think that 40-45 MPG with
a proper tune.

 

Im getting 38 average(city/highway) with a map,headpipe,Jackpots,PCV and SE air filter from Fuel Moto.

 

def get it on a dyno.
i get 35-50mpg on ours.

 

I'm blaming it on the cooler temps. I have 134 miles and my tank is at 1/4 full. Last fall in the warmer temps I did pull 37-39 mpg. I am also using the gas from last fall but I doubt that is the problem. That's with a 107 F.M. kit dynoed at their shop.

 

I am getting 38 mpg with a built 95" with 204 cams SE hydraulic timing chain kit and head work and I ride aggressive.

 

Man I hate to tell you but that's terrible fuel mileage. You should be getting 200 miles or more between fill-ups... I'm getting 40+ mpg when I stay out of it on my Street Glide 103/211 cam/Pro Pipe/Heavy breather/SERT

 

Fuel Moto's maps are weighted for performance and cooling with mileage a secondary concern. They can send you an "economy map" if you ask for it, but you can DIY by making some changes to the Fuel Adj. tables in the map. Before making changes to the map, make sure you save the original map by saving the map to a unique filename on your computer.

Open the map in the PC software and subtract 7% from both Fuel Adj. tables (front and rear cyl.) by selecting all values from 2000-3000 RPM and 5-20% TP (throttle position) and depressing PG-DN seven times. The values of all selected cells will decrease in increments of one for every keystroke (PG-DN). Save the file to a second unique filename and "Send Map" to the PCIII while tethered. You'll need to connect the 9V battery to do this.

Doing this will improve mileage as long as you are cruising and your wrist is not stressing the throttle too much. You should be able to get 42-45 mpg at 70 mph.
