I have the power duals on the 11 FLHTK, but also have the fuelpak and it runs great. Nice low end torque, much cooler.

 

So what you are saying is that every engine made has exactly the same performance and exact same tolerances. No way, ever heard of manufacturing tolerances? Those tolerances are the reasons that not every bike performs exactly the same. Because of that, there is no substitution for a tune of a dyno bike done by a compatent tuner.

Now granted, they are pretty close to all being the same. The maps that Fuel Moto supply are generally speaking very good and for the most part get the job done. However, I still stand by statement that they are not a "custom" tune. They are more like a suit seperate at the department store. A custom suit means I go to a tailor and have MY body measured and the cloth made to fit ME, not the standard measurements for size 48 jacket.

 

Of course I am NOT saying that ALL engines are "exactly" the same down to the tolerances, etc, etc. But on the other hand do those tolerances really matter in practical application when comparing two 2011 103cc FLTR's as an example. What I am saying is that the tunes Jamie provides as part of his total package and ongoing support ($499 out the door with the PV) are more than acceptable and unless you are doing something beyond recreational riding where every drop of horsepower and performance counts I would argue that paying HD for a race tuner ($500), paying for a custom dyno tune ($300) and then praying that the guy that did the tune knows what he is doing just doesn't make sense - especially with all the other things you get with PowerVision, like touch screen, automated diagnostics, new O2 sensor based auto-tune and the ability to reload, replace, update and manage your bike's overall ECM internals without paying $86 an hour each time you want to make a change is a way better solution for "most" of us that aren't on a race track. The key metric here is "practical application" vs. the money spent and the performance gained. The PV solution from FuelMotoUSA/Dynojet is just a better value for "most" of us - IMHO of course.

 

and the vance and hines high output mufflers will also work on the stock motor and run just fine.

 

i wonder if they are putting the O2 sensors in reversed on the v and h

 

I do not think that the power duals and Monster Rounds or the Oval exhaust would be a problem to tune on a dyno.
Got them on my 2011 and will have bike on dyno in another 300 miles ( 1K ) mark.
I will post and note any issues.

 

That will be good to see the results. I think the dyno tech at my dealer is new to the job, so that could be an issue. I haven't heard of anyone else having problems with the power duals.

 

I had my Power Duals Dynoed and the bike runs great. Dave at JD's drilled two small holes in the baffle of the right side pipe, and slipped the O2 sniffers up past the "X".
Your Tuner should be using sniffer tubes and not be relying on the O2 sensors for AFR readings.

 

Went thru the same issue a month ago running Pythons with the plugs popped out. Theres no right tune for it but Jamie at Fuel Moto sent me a starting point though I did add 255 cams. Went to the Auto Tune and haven't looked back.

 

My mechanic / dyno guy at the HD dealership installed my V & H Power Duals & Hi-output Slip ons on my '10 FLHX & tuned it and I'll tell 'ya it runs GREAT...absolutely no complaints from me in 10K driven since
