The Hanso 2014+ is what I used on my 2016 Roadster. I have the Ramair installed, along with Dave Platt cans and crossover pipe. Runs great on this tune, but I haven't had it to the Dyno yet. The one dyno guy near me is pushing the power commander also, even though his website advertises direct ECU tuning and lists the Rocket as one of the models. I think they just want to sell more stuff. Frankly, I don't see the point in a PC with my setup. If I went with headers, new cams, etc, then sure.
On Tune ECU - it still works fine even though it is no longer supported. I have no issues with connecting to my ECU through a Windows based laptop.
