I don't think they tuned it at all if you want my opinion. If they did they did a crappy job. Those lines look horrible. The HP and the TRQ lines aren't even to scale with each other. The air fuel looks like it's around 14.0:1 instead of 13.0:1 like it should be. Looks like they threw a MAP in it and made a couple passes to give you a printout and that was it. The numbers next to your name at the bottom are 7 and 8, so I would guess that's all the passes they made. A full dyno would take a minimum of 48 passes. Tha would be going through each cylinder 2 times, once to get samples to make the corrections and the second to verify the corrections.
That's ALOT of dyno time!!

+1, I have been looking for the right cam for the 106 and my indy swears by the 585. I had the 585 in my built 95" and didnt like the lack of pull down low. It was a animal above 3300 but below that it was a bit of a dog and I would always have to down shift and thats with the 5 speed. Also had a lot of pinging that we couldnt tune out?? He says its totally different in the 106 with the 10.0CR??? Would sure like to see the dyno.

Thats a beautiful dyno! I bet its a blast to ride. Thank you very much for info, I needed to see that. I was just looking at the tman 555 torque monster cam as well so its funny you post a dyno with a tman cam. Thats awesome!
That's what a proper tune takes. Keep in mind that that is not 48 wide open throttle pulls. That is 2 pulls (per cylinder in each of the throttle position ranges. TP ranges are as follows on most bikes, 0% (idle) - 2 - 5 - 7 - 10 - 15 - 20 - 25 - 30 - 40 - 60 - 80 - and 100% (wide open) Not all bikes have this many, some (like the V-rod) have more. Throttle by wire touring bikes have a 3 4 and 5. But they idle around 4 so you adjust 3 and 4 together without a pull. Not all pulls will hit the rev limiter either, 20% usually gets close but not always there, anything below 20% will be shy of the limiter. So a minimum (proper) tune will get hit the rev limit a minimum of 24 times. Like I said, this is for a thorough tune. Alot of places will throw a MAP in, attempt to tune the 100% throttle position to give you a good sheet and ship the bike. If you look at alot of these sheets, at the bottom where the run info is printed you will see some of them say "runfile" then a number. (i.e. runfile_006) Runfile is the default name that WinPep (DynoJet tuning software) names the runs. If the dyno operator doesn't name his runs, it'll default and call them runfile, the number after that (006 in my example) would be the number of that pass, in this case it wat the sixth. I name Front 1 (wide open) then the tp run (80- 60 - 40 etc). Then I make my adjustments and start new runs Front 2 then the TP runs. Etc. Then I move to the rear cylinder and name them Rear 1. You get the drift from here. When I am totally done with the VE runs i'll name 3 passes REFERENCE. That's just my system, but if I left them default to runfile I wouldn't be able to go back and see what the bike did at any particular run. Kind've hard to tune unless you are only tuning wide open throttle.
You can get alot more from a dyno sheet of you know what you are looking for. Hopefully this will help some of you.

harleytuner, how long of a wait is it to get a tune at your shop ?
I just loked at my schedule yesterday, I have about 20 bikes to get tuned right now, so I would say we are about 2 weeks out. We are really fortunate right now to be extremely busy. I know I have all those bikes to tune and 3 engine build to complete with more work coming in daily. Our other 2 techs are busy building engines as well.

Had my bike dynoed today.
70.73 HP & 82.39 TQ
Bike is stock except for Bub 7 slip-on's and XIED.
They told me if I were to add a less restrictive A/C and have it tuned I may get another 5-7 hp.
If that's correct I'll leave it as is.

Less restrictive SE air box is about 150 bucks, about the cheapest 5-7 HP you'd ever add to your bike.
