Diablo for 2013 Silverado
Purchased this in hopes to improve mileage during my DD and to add hp and TQ for when I tow my trailer. You certainly can feel a difference. (I do have a K&N air intake and an MBRP cat back. I look forward to using the tuner with the trailer. I never had one before, It seems light but that's good for hanging on the windshield. Easy installation and decent size screen. I am still getting used to it but the gauge option. Will try Diablo forums.
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.
