a power commander is different than the JB and the Area-P tuner.. They are all made by the same company though, DynoJet.
The JB and the Area_P tuner are say the base models, no options on them, cant add any options on them, they only adjust the fuel.. A power commander is say the middle class, you can add on a bunch of options to it, like the quick shift or the auto tune and there are some others as well, it also adjusts your fuel and timing..
The JB is a generic map put together by Two Brothers, we called this a "canned tune" it works well for anyone.. You get one basic map and thats that, end of story.
The Area-P has been doing a BUNCH of research and right now I believe they have I think 9 base maps.. Now when you order a tuner from they they take one of the base maps for you and then modify it for your needs, they take a bunch of factory into account and custom make it for YOU. They also include free lifetime support, so if you change a mod, they will change your tune.
A Power is really a mix of the two...Unless you get a auto tuner or dyno tune the bike yourself, your stuck with the maps they provide you. There is no one to modify the map if your mods dont match the mods listed on their website.
This is why I chose Area-P the customer service is amazing, and after installing the tuner it was just crazy how different the bike felt. They are going to do further testing here in a couple weeks for the pod filters, I cant wait to get my final tune for that
