Live mapping or dyno mapping?
Discussion
They can both cross over.
Live mapping is where the info to run a car is changed in real time, and is common on standalones, and some older ECUs (where you fit an chip emulator inplace of the chip), but there are ones about where you can't emulate the chip, or the software runs constant checks on the data integrity and it might assume the memory has become corrupt.
Usually live mapping would be done on a braked dyno, at a steady road speed, and you'd alter the data and see if the car speeds up or slows down (or listening for knock), and that would then be done time and time again for different RPMs and loads.
The other style would be to do a dyno pull, change the map a little, run it again, change it, run it until you'd got the best power.
I would say you'd find bigger differences between who did the work than between each style.
You will also find some people who do it on the road by driving it, but the person doing the work would be the most important factor.

It's a little bit of swings and roundabouts, road mapping has better cooling, you could do it for hours. Dynos will be more accurate as you can stick at a given RPM at full throttle and see what happens.
On the road, you'd drive through that rpm point and accelerate.
Best bet is the email the guy and get his side of the story for road mapping. You could say dyno mapping is done by finding out the settings for the most power, road mapping is done by watching the fueling and setting the ignition timing up at a safe distance from detonation (ie setting up for the best AFR and ignition).
In both cases, they should be similar, as in best theoretical AFR and Ignition = best power, although that isn't always true.
Both will be able to give you good results, but road mapping would have a greater need for experience.

Certainly a lot more important is the ability of the person, rather than the method.
Dyno is certainly a more controlled and safe environment and easier to get a measured response for any changes made. But of course that means it isnt a road, and you do drive on a road.
Ultimately things will have to be finalised on the road.
