OZ omega tune with RTD4 tuner

[jridout325]

Looking at getting the OZ Omega tune during the black November sale. Does the HP tuners RTD4 allow everything to be done through the OBD2 port under the steering wheel now? I know in the past you had to go under the hood and disconnect the ECU. Looking to avoid that if possible. How simple is the RTD4 method? Just wanting to eliminate cylinder deactivation and improve the drivability of my truck. Thanks for any input.

Of what I have read everything is done through the OBD port now. Just send them an email to be sure.
