No doubt Nistune has some advanced features but I have been happy with my combo. My only objection is that I can't actually do live changes. When you are in emulation mode and edit a setting, you should be able to save it in real time. Doing that causes the ECU to fault until you restart it. So I have to shut the engine off to save program changes. This is only a minor issue especially if you are tuning alone since you can't (shouldn't) make edits while driving anyway.
