as a consumer, I would want a copy of the finished calibration. as someone who fraternizes with tuning types regularly, I think most reputable ones will provide the finished calibration at least upon request.
Other side of that coin...
I get my bike tuned for $$$$ I have paid for that tune/service just like any other and it is mine to do (give) to whatever I want and not for the dyno operator to use again to start tuning someone else’s bike. Is it fair for the dyno operator to use it as a base (instead of starting from scratch) to tune another customer’s bike charging them the same they charged the original guy to tune his bike?

good question. I would say that everyone who is thinking about paying for a dyno tune should keep in mind that there are three things you are really paying for and the length of time in regards to labor is the least expensive of the three. The tuner may save some labor time by using your previously paid for calibration to use as a starter calibration for the next build, but easily the most expensive thing that the dyno cost is going towards is the equipment. There is a never ending expense to a dyno tuning shop when it comes to equipment. There’s always something else that needs purchased or replaced, and nothing is cheap. In addition to time and equipment, the most valuable thing that you are paying for is the tuners experience. Experience comes in a variety of forms, and that can also come at quite an expense. Just about every tuning system on the market has courses available at a cost for the tuner to get a better understanding of the products that they are using, none of them are overly cheap as far as I know. Some pro tuners like fltri, Joe_lyons and hrdtail even puts long hours in on the internet discussing their craft and honing their skills, all in an attempt to provide a better service to their customers. The experience portion may include work that they have already done, but that is also helpful in knowing if the particular bike that is on the drum is behaving as expected or if there is a potential issue that the tuner has to search out. An experienced dyno tuner can get the job done faster and with less stress on the bike, but that doesn’t mean that you are getting a lesser quality tune.
Let me ask a question which is almost the opposite of the above, would the average consumer want the tuner to start from scratch on their bike or would they want the tuner to use something that they have already had good results with? I would think the verification and less wear on the bike should have some value.
