Bike is a 2015 street glide with Fuel Moto 107 kit. 10.5:1 pistons, 999-6a cams, level B heads, D&D Fat cat exhaust, and a Power Vision with autotune. I am running the tune from Fuel Moto with a couple of auto tune sessions. The bike runs strong and is fun as hell to ride.

The dyno run was done at my local HD on a Dynojet dyno. They wouldn't let me in the back to watch, but I assume it was done in 6th gear.

My numbers were 106hp/ 112tq. This is 13hp/ 13 tq lower then I was expecting based on an identical setup on Fuel Motos site.

A couple questions

1 Can the difference in power just be the difference between dynos?

2 Why is the torque curve so different between the charts?

3 Any problems/ issues to check for?






Fwiw my buddies 2015 RGU CVO with SE cams, intake and true dual exhaust did 97/107 on the same dyno.

 

From what you posted it sounds like your bike had a dyno test, the FM bike was dyno tuned.... big difference. On your dyno run nothing was done to optimize the tune.

You need to go somewhere where they will make the needed adjustments.... dealers are very reluctant to do that.

RRP is right. If you tuned it yourself, it's likely the reason for the Tq curve difference. Still, Gear run and Dyno are also likely additional reasons for the difference in 2 maps.. The fact that yours is in STD and FM is on SAE should make yours stronger by about 2-3%. (It don't)

 

Yes I'm aware that I only did a power run. The tune created by Fuel Moto for the bike on their dyno chart is what I'm running on my bike.

 

You mean the numbers were not as advertised by the seller of the kit that he got on his own dyno? That is why I always look for 3rd party dyno numbers and it helps to get a couple of different ones from around different part of the country. If the seller's is always the highest. Red flag.

 

Call Fuel Moto!

 

Not so much concerned that I didn't have the same numbers, I know they vary for a bunch of different reasons. However, I am significantly lower and the torque curve is very different, I'm just concerned that I may have some sort of issue

 

The first thing I noticed is the correction factor is different. SAE vs STD. That will yield different results. Also I couldn't tell what gear the FM dyno was tested in. There could be a significant difference there also. 5th vs 6th gear. Your Dyno was done in 5th gear, look in upper right hand corner, is reads "smoothing 5". As long it runs good and no de-cel pop and the AFR is in spec you should be good to go! I would recommend letting a good tuner get ahold of your bike so they can optimize what you have. I have a "canned" tune from FM in my Road Glide and it needs some massaging. Dyno and tune is scheduled next week for mine.

 

A couple of other things. STD usually reads 1-2% higher than SAE, and smoothing factor has nothing to do with gear ratio or gear selected. To compare gearing. Gear ratio can be displayed. Bet they are both around 38-40.

 

Get it properly tuned and you will see some gains. You're not to far off of what I typically see out of that build. What's are you located? Perhaps some of the members here can point you in the direction of a reputable tuner
