Alright........I did a couple of mods. 2007 Road King. I put on Reinhardt slip ons and a stage 1 air filter assembly. I did these to push maybe a bit more MPG out of the beauty.

Last ( because I was told it would be a good idea ) I forked out the $170 to have the Stage I MAP programmed in. My MPG dropped from44 to 38. I am pissed[:@]

I drive my baby 130 miles a day comuting, and then my play time. I want my MPG back with as much dignity and wallet as possible.

Any help

 

Once you made the decision to allow more air/fuel to run through the motor, higher fuel consumption is normally the byproduct of the modification. Some will say that their mods have given them a little bit higher mpg, but that is probably the exception to the rule.

In my opinion, the only way you can get a little more mpg out of what you have done is to start short shifting the thing. But that probably isn't why you modded in the first place.

One or the other. It is hard to get both.

 

There is that fine line of "more A/F" and better effieciency of delievery. I am going for a more effiecient bike. I didn't mind the power at all when it was stock. I love the sound with the S/O.

Hell, to boot, I didn't even gain a noticeable power gain with the Stage I MAP.[:@]

 

The maps suck and are very Generic, get Thundermax (self-tuning) or a PCIII in which you will need to adjust the map to get the best MPG.
