You know it's rich at 55 so figuire out where that is in the map like was stated in my early post. And lean it out and around it and smooth it out. Say 6_8_10_ 8_ 8 so that it makes it work in your bikes. It's going to be mostly a curve threw the map that matters most the rest I talper off in the derrection it is. 20 then -5 becomes 10 _ 8. You should be able to have your own custom map in a couple weeks that runs better and cleaner. You don't want to keep running rich it will cake up your pistons and heads.
Timing can be changed if needed , I had to take some out that was added in the dyno jet map that was carried over to the dyno tune. This is bad if you have detonation which when small you can't hear but you can see small shinny specs on the plugs. Mine was at full throttle after RPM rise.

I hope you realize that all this dynamometer jabber is just nonsense for almost everyone. It is almost exclusively a way to separate you from money you do not need to spend. The tuning specs available from DynoJet, Fuel Moto or any other similar outfit are all anyone needs for road use even if you like to be heavy on the throttle to impress whomever, yourself or others.
The specs DO NOT have to exactly fit every damn modification you have made. They simply must closely approximate what you have done to your cycle. Only the guys whose sole reason for being is to talk an extra few horsepower or pound-feet of torque extol dynamometer testing. To each his own--but, I think they are goofy having bought the line that costs them lots of money, but does not achieve much or any value.
I can pull the front wheel off the ground in second gear with my 2006 Ultra and it never has seen a dynamometer. And, I am not an expert rider by any means.
Tons of valuable information can be gleaned from the great folks on this forum. I have learned alot here. The dynamometer folks are not among those whom you need to listen to.

If I'm not mistaken NASCAR teams tune and store maps for various engine configurations and tracks so that they can simply download a map that they have already tweaked for what/where they are running. Of course nothing's really thst simple but you get the point. To continue with the NASCAR analogy, I'd bet Richard Petty and crew tuned for years without benefit of a dyno.

In late '02 when I bought my '03 Ultra Classic I went with Scotsman heads, 95", S&S 510G cams with a PC3.
It made 95/96 on the dyno. I was not satisfied with that and switched to 37G cams.
Went to 98/98 on the dyno, but then starting having severe detonation issues under load in high temps.
Tried to get it tuned right but power went down.
All these years later I am still running the same rig with 26G's and the original PC3. Bike runs perfect, 90/90 hp & tq . I'm happy with it and still keep up with the newer bikes.
A decent dyno tune should not cost more than 2-3 hundred dollars.
Better you blow the motor up on a dyno than out on the road, just sayin....

Guys guys..what did I start here? All I originally commented on was about the ridiculous cost of the only local dyno tuner in my area. The reason I was looking to get it done, was not for horsepower or torque but to have the bike run its cleanest and most efficient given the mods I made. I noticed a large decrease in fuel mileage. I'm not &itching at the cost of fuel, other than it seemed excessive. A clean running efficient running engine will last longer then some behemouth belching out black smoke. That's all folks. Nothing more or less other than the rant about the cost of a dyno in my area. My bike runs good but I'm a perfectionist and given what I have to work with, I would like the best possible within reason, and $850 is not with in reason. My gosh ive seen guys get their periods on here just talking about oil.

Roussfam,
If my dynamometer opinion did not already **** them off, I doubt nomenclature would push them into cardiac arrest.
Funny.

cajun--should have seen that comming, like an oil thread. lol
yep at some point I broke down and didnt care about price,hp, or what ever...just wanted a perfectly running bike and would have shipped it to califonia if i had to....perfection.That will always haunt you.
btw with my mods i did make a nice gain 10/10,tuner said he could double that if i changed to performance pipes...never did.
