Good tuner did what it was supposed to. Easy to use.

Installed the 91 octane tune on my 2014 Ram 1500 and yes I did feel a difference but not a 600 dollar difference. I plan on getting a custom tune from Hemifever tuning to make the thing worth its money. Its cool that you can take off the speed limiter and adjust a lot of things to you needs. I would recommend buying this through Hemifever.com with their tune already preloaded on it instead of just using the diablo pre-set tunes.
