My Ultra was getting 40 MPG with FM stage one; ever since 1st service I'm lucky to get 36 MPG.

 

Got about 43-44 mpg on a ride last week. Temp was about 65 deg. It seems when it's warmer my mileage goes down a bit, but still usually at least 40 unless I really put the hammer down.

 

I have a 09 Street Glide with rush 2" baffles and big sucker. SEPST I used Smart Tune and tuned it myself. I normally get about 40mpg around town but spend alot of time way down in the throttle. Last weekend went ot the Blue Ridge Pkwy with wife and rode real easy as she doesn't like heavy acceleration. Got an unbelievable 48.1mpg on a 320 mile ride. I am pleased so far.

 

2007 FLHX with Stage 1 SE AC, PCIII from Fuelmoto and Vance and Hines oval slip ons. I'm averaging 38 mpg in mixed riding. I had a V&H fuelpak on prior to the PCIII and was averaging 42. I'm a little disappointed in the drop in milage, but the throttle response seems to be better with the PCIII.

I average just at 38mpg on the crappy ethanol mixes in Missouri, the Fuelpak, HiFlo A/C and Monster Ovals had very little impact against the stock setup for me. I did get upwards of 41 for a time in the spring months just after we bought it but then the ethanol percentages went back up to aid the state farmers. Outstate in Illinois I did find 92 octane w/o ethanol and got 42 on the setup I currently have.

 

Just finished my first tank of gas with my FM stage 1 package. Mileage dropped from 43 stock to 32 now. I don't believe I've been on the throttle any more since I've added the setup. Exhaust headers turned very blue also. FM is sending me another map for mpg. I hope performance doesn't suffer with the mpg map because it sounds better (not Rinehart better, but better than stock), and has better performance than stock with stage 1.

 

I was getting 44 mpg riding 2 up with a stock 96 with D&D slip ons. I recently added a stage 2 103 build with screaming eagle super tuner, V&H power duals and V&H twin slash ovals. Now i get 39 to 42 mpg riding 2 up.

 

I get between 37 and 38 riding 2 up with all the upgrades in my sig.

 

I ran my SG stock for 1 year and could get maybe 45MPG running 75MPH. Since my FM upgrade Rinehart slip-ons, A/C and PCV I can get 40MPG running 75MPH, if I go 60-65MPH I can get close to 45MPG.
