I just got a cortex tuner thats loaded with the rotofab tune as well. I also have a catback system and my question is do I need an update or something else for the catback set up?
Cortex noob, have a question

I don't think they have any changes for exhausts. When I bought the Vararam tune I never noticed exhaust tunes.
The only real way to benefit from mods is a real tune. The Cortex is user friendly. Even though you can return to stock the dealer still knows someone has altered the ecm.
