After switching to Power Vision on my Harleys (FXDWG and FLHXSE2) I can assure you that, apart from going to the bench (well done...), it is the best system for adapting the ECU of an engine to various hardware modifications but also to your driving conditions (ambient temperature, humidity, altitude, etc.). There is even an auto-tune option for guys who are not used to the tool. It's a shame that this doesn't exist for the Rocket because this tool allows you to touch almost all the injection and ignition tables, modify the displacement, take information for the tachometer, etc. For the moment, the best quality/price ratio is still Tune Ecu with Penner maps...
With Power Vision, no more "pop" when decelerating and a closed loop retained for constant speeds which allows you to have low consumption while having maximum power the rest of the time... Too bad Dynojet does not offer it for the Rocket 3.
