Maybe there is someone out there that can help me a bit on this. I have a 2011 DX and had the exhaust done by VMod, K&N filter and added a PCV. I had the bike dynoed at it came out to 99 at the rear wheel. Do these numbers look correct for this type of mod or not? I know that people out there exaggerate on their numbers all the time so not sure what to compare it too. I didn't have any maps at the time so the shop was the one that installed the map. The bike seems to be running OK, no pop or hesitation. If the numbers don't look correct should I try another map and if so does someone out there have one? I couldn't find one for my exact configuration. Thanks:notworth:

I have a 10 DX and I drilled my exhaust everything else is stock. The HD shop by me was having a bike night with a dyno shot out so I intered by bike I had 111hp and cant remember the Tq but the fuel to air was still good after drilling the pipes. 90 hp sounds a little low for what you have done.

What color is you 11

A lot of that depends on the dyno, and the conditions at the time. If the bike runs well I wouldn't sweat it.

Edit: there is a member called ibrown that you should chat with, he tunes Harleys and knows dynos.

one thing is that the numbers on a factory or superflow are about 10 to 15% lower than the numbers on a dyno jet...if the bike was tested on one of those that is about the number you would get..a before base run would have told the story.. i think i would ask them if they have any runs of stock v-rods on their computer that you could compare your runs to..

Thanks for the information. I will find out what dyno machine they have and will go from there. I think I might get the CFR's later on so I'll know if there are any major differences once I install those. The bike seems to be running good so that's what really matters.

It's good to have knowledgeable people on board, thanks again.

Dyno Sheet

Here is the Dyno sheet with the actual numbers. Up until now the bike is running fine and I don't see any problems but I really don't know much about these numbers (fuel/air ratio) although they do seem to be constant thoughout the rpm range. Don't know if that's good or not.

The bike was still cherry at the time of the Dyno (800 miles). Don't know if that was a factor.

the numbers seem a little low.. but dyno`s all get different numbers.. he was using sae correction factor,, most dyno operators use the stp correction because it is a few percent higher and would probably have shown about 3 more hp..there are 3 runs with a large difference in hp.. what was the setup on each of those runs? i would be curious to see the numbers from a completely stock bike on that dyno.. that would be a good measuring stick to compare your hp to..

That's not your run. Look at the date of the run file on the bottom

Crazy low! My stock (BONE STOCK) 09 AW did 105 at the homecomming at KC. It might run ok, but the tune is leaving out some power. JMHO, Joe

Unless the tuner has no idea how to date it, that says 04. Hal is right! Good eye, Hal! Joe

Yup, The DRF (dyno run file) is time stamped by the computer time setting when it's saved.

Dyno

I had asked them about that and they stated that the tech hadn't set the date parameters.

with all due respect but if the tech can't set the date on the dyno then i damn sure wouldn't let him tune on MY bike.

Dyno

Yep, I'm with you on that one. I think I'll be taking it somewhere else for another run.
