Vance & Hines Power duals - can't tune on FLHX
#12
Ahhh...grasshopper....but you make the assumption that the tune is a canned tune when in actuality it would be a tune from a bike that Jamie actually dyno'ed in his shop with the exact same configuration as the one the OP was talking about. Year, make, model, breather/air cleaner, pipes, etc. Then Jamie saves the map from the actual dyno and then gives it to his customers as part of the deal. So you see sir, it's actually a pretty good approach. Now, granted, if you have some super duper custom engine work or some high performance custom engine mods that is something else - but we're talking about essentially a stock ride with stock bolt on mods where one dyno map should work on two identical bikes assuming the components are the same. Check it out for yourself - you might change your "tune" - LOL. Just sayin'.... ...and by the way, when I say "custom" tune I am referring to Jamie's personal stash of dyno maps - not the "canned" tunes that come from DynoJet already installed on the device.
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.

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.

Got a set of power duals and high out put slip ons trough my local harley dealer, bought as a new package with bike.
Only problem is they can not tune the bike with these power dual headers on.
Have swapped different slip ons and still can't tune in. Seems there is not enough bottom end back pressure, ok at 2500 rpm and above. So they have put the original headers back on with my high output slip ons and presto it runs beautiful.
Has anybody here had trouble with the power dual header pipes?
All Vance & Hines tell me is they have no trouble tuning this setup with their fuel pack. Surely the problem isn't in the tuner?

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.
