I decided to take my FLHX 103 down to the dealer to have a baseline dyno run completed. I never took it when it was stock so I don't have comparison numbers for my specific bike but I do have numbers for a similar FLHX with the 103.

Here are the upgrades I have completed on my 2011 FLHX 103:
- Arlen Ness Big Sucker
- Vance & Hines Power Duals
- Rineharts 4" Slip-Ons
- H-D Stage 1 Download

I am looking for some feedback for the results. I don't plan on doing any further motor work I am very happy with the power, performance, loss of heat and gas mileage at this time.

Any feedback is appreciated! Thanks in advance!

 

do you know what gear they do their base line runs in? If that is in 4th gear it is about right for a stage 1 103 if it is in 5th or 6th perhaps just a smig low. Did they not do an afr?

 

I think you need a tuner. PC-V or even a Sert.
