took me 3 minutes. This is one of those rare items that works! 2013 Jeepo grand cherokee is now responsive as a v8! no joke. i have oversized tires that made my GC sluggish. this feels like a 30HP jump. seriously. it has many setting or can be turned off. I love this! best purchase yet for an upgrade to my car WITHOUT messing with the engine or air intake( which in my opinion does nothing but make your car louder)

This tuner is really is everything it's advertised as. I don't use many of the features yet but with a little tinkering it's easy to navigate the menu options. The performance tunes work really well. Really woke of the 5.7 HEMI in my Jeep. All touch screen and if you want to make it your primary monitoring system it mounts nicely above the dash. Highly recommend this for anyone looking for some extra performance or even wants to get a little better gas mileage.
