It's simply about riders sharing their personal choices and experiences with various products. I've now had experience with four different tuners and to my surprise Power Vision has given me the best results. It's also quite simple to use for those of us who aren't software engineers. lol
The first time I tuned with a tuner it was harder. I cut my teeth on that one and moved to the next. That one was easier. Was it because the system was easier to use, or because I had more experience? I would go with the later because..... There really isn't much difference going from one flash based tuners to the next. Sure things have different names, and you move around the program a bit different, but...Like I tell most guys. If you can tune with one flash base tuner. You can tune with them all.
Now, if you are tuning a, not the run of the mill combo, or you run into problems, or not a close base map to start with. I know which tuner I want. The one that gives me the most flexibility. I am past the point of learning how to use the program. My customer service calls are past "what's this table do."
