What benefits do you want from the exhaust? more power, economy or noise?
The standard ECU is restricted by emissions controls. Tune ECU piggybacks on the standard ECU.
I have a 2013 690 SMC R with a Vortex on it. One Vortex replaces 2 KTM ecus. Much more power and torque, mpg goes down a bit but the bike is transformed.
I use only 3 of 10 available maps: Power, torque and economy.

Instant throttle response. No sudden scary unwanted acceleration in heavy traffic.
