Don't worry about the short time on the dyno. Your setup is is basic a/c and pipes. If he's a good tuner he simply loaded a map he's been tweaking for years that matched your setup. A few tweaks for your bike's specific needs and it's good to go.
The most important thing, as others have mentioned is, are you happy with the way the bike runs? Are you happy with the fuel mileage? If you are than your tune is perfect.

I am perfectly happy with it. I just want to see what it does when the weather cools down because yesterday was really hot. I really could care less about fuel mileage. That comes second to me. I'd rather have my bike a tad on the rich side anyways.
If I really cared about what exactly was done to it, I could just go into the tune and look at all the numbers and compare them to the numbers of the old tune, but it's not that serious. Jaime from FuelMoto is pretty recognized and that's where I got the previous tune from, but it wasn't for duals. It most likely was pretty spot on and just needed some minor tweaking.

r8rs4lf,
my tuner also took about an hour and 20 (or so) minutes. 8 hours to tune a bike seems completely too long to me. I agree with the poster that mentioned most tuners go with what they have and just tweak the map for your specific bike. or at least that's what i've seen. I remember taking a friend's rocket 3 to get tuned. the guy took quite awhile because he really didn't have his own map to start with. he was working off the dyno "stock" map even though the bike had slip ons and a k'n air filter.

I took my bike on a longer ride today and can definately tell the difference. It's like night and day. Real smooth through the band and powerful when I hit it. The sound is just phenominal! I'm definately happy with the results of my combo and how the bike has been tuned.

Well I finally got a chance to get my bike to the dyno. It didn't work out like I had planned, but it seems I did go to a rather competent tuner. It was just a bit out of my way.
What I'm working with.....
-'09 FLHT
-Factory 96" motor (no internal mods)
-PC-5
-V&H Dresser Duals
-CFR mufflers
-PM AC w/ K&N
I called my initial choice for my tune and got the run around. Didn't know if they could get it done, couldn't get ahold of the actual tuner to ask him, blah, blah, blah! Well, they just lost my business. Too bad because they were about five minutes from me. As the barber said, "NEXT!" Called another recommended tuner, couldn't fit me in. Booked till next Wednesday and rightfully so as they came highly recommended. Wasn't too upset about that one as it's my fault because I wanted it done ASAP.
Ended up taking it to Mickey Cohen of Mickey Cohen Motorsports located in Placentia, Ca. (714) 276-0478. Had many, many race cars and bikes there.
Dropped it off at about 11:30AM. He told me to come back in an hour, hour and a half. He actually said go get some breakfast or lunch and come back. Cool guy for sure. After eating lunch, called him. It was about 12:45PM. Said it was ready, come get it.
When I got there I asked him what it was like before he tuned it. Told me the AFR's were all over the place and something about the torque. Can't remember off hand. I'm going to call him to see if he has anything on his computer from before the tune so I could compare.
Anyways, here's the sheet.
Let me know what you think!

Also, 3 hours max for tuning with a PC. The SEST, SERT, etc. are longer with a competent tuner. IMHO of course.

KWS motorsports is a huge dynotune/sportbike/race center about 2 miles down from my house. They're known all over the sportbike/drag race world. Race teams, have race teams etc etc.
The owner - Kevin - who dyno tunes 1000's of bikes for competition once quoted me 225 and 2 hours to tune my Harley. He does a lot of those too apparently. I asked him how much for say a Busa or a Gixer? Told me 350-500 4 hours or more. I asked him why the big difference? Are the sportbikes that advanced or hard to tune? He said:
"That engine configuration [Harley] has not changed much in the last hundred years but the major difference is you only have 2 cylinders and it only revs to around 6K RPM. Anyone can tune one in a few hours."
I also got out of him:
"If you are letting someone bang on your bike for 4+ hours to tune only two cylinders, no variable valve timing or exotic heads/cylinders, on a low RPM engine, you are paying them to learn and you're getting ripped off."
Kinda made sense to me.

Always difficult to compare dyno sheets but if all were equal your sheet imho is about average, actually a bit low. My findings are about 75/88 but it really depends on how you think it runs.
Also, 3 hours max for tuning with a PC. The SEST, SERT, etc. are longer with a competent tuner. IMHO of course.

I think the majority of people think tunes take around 3-4 hours when in reality that is just what most shops charge. Almost like a minimum charge if you will for using up time on the dyno. And of course the shop isn't going to call after after an hour. This is just my opinion of course.
I took my bike on a longer ride today and can definately tell the difference. It's like night and day. Real smooth through the band and powerful when I hit it. The sound is just phenominal! I'm definately happy with the results of my combo and how the bike has been tuned.

that is a very good point. because when he was writing me up he charged 3 hours I believe. it was 325 for doing separate cyls' and he added some timing.

Doesn't make sense to me. Different tuning devices and different combo's take a different amount of time. Tuning a PCIII or PCV with Tuning Link with a map in basic mode probably takes an hour. Bump it up to an advanced map and it takes longer as you are doing individual cylinders. Now work the timing tables and again it is adding more time. On the other end take a 117, 120 or 124 with high compression, high overlap cams and a big throttle body. That can easily take all day. WOT doesn't take that long but working the areas where the bike spends most of it's time, takes time. Anybody that tunes a bike with a TTS or SESPT and does it in less than 3 1/2- 4 hrs is either extremely good or hasn't done a proper tune. Just my .02.

My bike is basic, so a basic tune was in order. I more than likely got charged 3-4 hours, but it was done in 1.5. Does it bother me, not with the way the bike runs now.
The thing that gets me is when people are misinformed that a tune should take 3-4 hours just because that is what the shop is charging. These guys who come highly recommended are making a killing on their tunes. It's all pretty much the same, just minor tweaking. And when a guy comes in there with a different set up, it may take 3-4 hours, but believe that tune will be saved by the tuner to use the next time round so it won't take him 3-4 hours again.
That's another thing, how competent is the tuner. Many different variables it seems.
