Great product for quick gains
As soon as you get this, go through the instructions carefully and make sure to download and update all of the software. Truth is these things can sit on shelves or in warehouses and be out of date. After all of this is done it is easy to set up and go. This tuner has excellent features including a factory back up that can be installed back at any time. Once I installed mine, I noticed hp gains especially in gears 1-3. I have a 2014 Challenger Shaker with the 5.7 Hemi. Love it!
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.
