The key to consumers is finding a reputable technician to do the dyno tune. I have a TTS on my SERK and tuned it myself after changing the mufflers and AC. It took a great deal of time, and learning the tool and science behind tuning - that I mostly enjoyed. The bike ran great for several years and many miles.
I decided to change the cams and lifters but didn't have the time to perform the work and retune the bike and have any hope of putting miles on her. Therefore, I selected a local dealer in Louisville with a dyno to do the work and tune. I interviewed the Tuner and he explained his process and all of the key tables that need to be adjusted to get a proper tune for performance and mileage mix. I felt comfortable that he knew what he was doing - plus they have a dyno!
Jumping ahead, I picked up my bike 3 weeks later and was very disappointed in the tune - excessive decel popping. I reviewed the map looking at the changed cells in all of the tables. He didn't touch the timing, placed the bike into open loop, and the only AFR cell changes were in load areas that you never touch while riding. I asked him about it and he told me the popping is a characteristic of the cams, pipes, and AC that I chose and not to take it out of open loop.
From my admittedly limited tuning experience I thought that sounded like a bunch of crap and I couldn't trust them to do it right. So I refreshed my memory on the TTS tuning method, retuned it in a few runs, including some timing chages. I now have no decel pop and a smooth running bike that can adjust for atmospheric and elevation changes in closed loop. Having tuned it myself I don't know the hp and torque numbers. It would be great if I could find a Tuner that is proficient with the tuner I select (that is key). However, the experience has reinforced my belief that the only dyno that matters is the one in your seat.
