I would suggest doing some homework. For example, it would be good to understand what "auto tune" actually means in terms of a PV. It actually doesn't really "tune" per se. It attempts to calibrate you VE tables and it can only calibrate the areas in those tables that you can hit while riding on the road. I'm not going to open a can or worms here, but there is a lot of debate on this subject, particular auto tune and wide bands.
