Immense improvement in performance on initial tune. I am really quite pleased.

The DiabloSport i2 tuner is easy to use with simply touch screen menus. Not a lot different than using a smart phone. A simple MPG tune improved my 2014 Silverado's highway MPG better than 10% with a 3.5 MPG increase and noticeably improved performance, idle, and shift feel. I look forward to trying some of the performance tunes in the future.
