I'm using I2 tuner (2014 Mustang GT 302) with the 93 octane tune with free tunes for life. To date it has worked flawlessly. I am thinking of adding headers and would like to know do I have to have a new tune. Thank you for a great product. I might add I only use a Apple laptop.

Thanks 06montyss

I will be storing my Mustang for the winter. It has a 93 octane tune, should I go back to the stock tune? Battery will be removed during storage. Thanks.
